Rat Poison and Our Pets

This time of year there are many pests outside and consequently we have a lot of pets that are exposed to ‘rat poison’.  For some reason, dogs especially are attracted to many of the products that we humans use to keep mice and rat populations down on the farm and around our homes.  They eat the product (unbeknownst to us) and then it may be days before they act sick.  At this point, it may be difficult for us to save the pet.  We will dive into the products today and give you an overview of the major products out there and their potential consequences.

  1.  The anticoagulant rodenticides.  These products are eaten by the pest and over time (1-3 weeks, typically), internal bleeding will cause death.  The same fate happens with our pets, if we don’t catch it in time.  Signs of rat poison toxicity:  Weakness, lethargy, pale gums, loss of appetite, difficulty breathing, coughing, difficulty walking, sudden death.  To diagnose the problem:  Physical exam, bloodwork (including a panel to check for blood clotting ability), x-rays and ultrasound may be necessary.  The treatment:  Vitamin K, supportive care, and potentially a blood transfusion.  The prognosis:  Good if found early on, especially if treatment starts before your furry friend is acting sick.  The rodenticide products (courtesy of “Clinical Veterinary Advisor”, Etienne Cote):
    1. Warfarin.  Trade Names:  Anchor Rat and Mouse Bait, Cat-in-a-Bag
    2. Pindone.  Trade Names:  Purina Rat kill Soluble, Eaton’s AC Formula 50.
    3. Diphacinone.  Trade Names:  Assassin Rodenticide Bait, Exterminator’s Choice.
    4. Difethialone.  Trade Names:  D-Cease, Generations, D-Con Rat and Mouse Bait.
    5. Brodifacoum.  Trade Names:  D-Con Mouse Prufe III, Havoc, Jaguar, Final Blox
    6. Bromadiolone.  Trade Names:  Boot Hill, Hawk, Just One Bite
  2. The bromethalin rodenticides.  These products are also used as bait for rodents, but act in a different way than the traditional anticoagulant rodenticides.  These products affect the nervous system of the animal, causing muscle tremors and seizures and weakness.   These signs start quickly, within the first 24-72 hours after our furry friend eats the product.  Treatment:  There is NO treatment or antidote for this poison.  We can try to get the pet to vomit or pump the stomach to stop absorption.  We can give supportive care (IV fluids, etc) to pets that are showing signs of ingestion, but at this point the prognosis is guarded.
  3. The cholecalciferol rodenticides.  These products are also ingested as bait for rodents and are as insidious and deadly as the bromethalin rodenticides.  They cause weakness, lethargy, and increased thirst and urination.  The kidneys are affected and shut down over several days.  Treatment: There is NO treatment or antidote for this poison.  We can try to get the pet to vomit or pump the stomach to stop absorption.  We can give supportive care (IV fluids, etc.) to pets that are showing signs of ingestion, but at this point the prognosis is guarded.

We highly encourage you to keep these baits out of reach of your furry friends!

If you have a pet poison emergency, please call us at WCVS or call the ASPCA pet poison hotline (888) 426-4435.

Feline Leukemia Virus – What is it?

This is such a complex and potentially devastating disease.  We get a lot of questions about it from pet owners, and frankly it can be tough to diagnose and manage Thebes the Catfrom a clinician’s standpoint.  Let’s see if we can clear up a few mental fuzzies about this subject today.

This disease affects cats ONLY.  This means that it can only be spread between cats and cannot be passed on to humans or dogs.

The virus is transmitted through close contact with an infected cat, i.e. cat bites, grooming, sharing a litter box, food or water dishes.  Saliva is the primary carrier, but blood and urine and feces and mother’s milk can all carry the virus too.  Many cats are infected as kittens, whether still in the womb or through nursing and close contact with an infected mother.

After a cat is infected, several things can happen.  

  1. Cat’s immune system responds and fights off the virus, clearing it from it’s system.
  2. Cat’s immune system responds but cannot fully fight off the virus, and it stays hidden in the body as a ‘latent’ infection for years.  These cats do not act sick, and can live a normal lifespan.  They can also live for a number of years and then eventually become actively infected and ill.
  3. Cat’s immune system cannot fight off the virus, and ends up with infection throughout the body, including the bone marrow.  This is life-long and cannot be undone.
    1. Bone marrow infection can lead to secondary infections because the immune system is not working properly.
    2. Bone marrow infection can also lead to anemia and platelet abnormalities, which can lead to weakness, blood loss and eventually death.
    3. FeLV virus also causes a variety of cancers in cats by ‘turning on’ cancer activity in normal cells.

 

How do we know if a cat is infected with FeLV?   Veterinarians have a quick blood test called an ELISA that tests for the virus in the bloodstream.  It is a good screening test for cats that have the virus active in their bloodstream.  Any positives should be followed up with another ELISA in 2-4 months, or a different blood test called an IFA.  An IFA test is different from an ELISA because it detects a positive infection in the bone marrow and is a good confirmatory test.  This helps to determine if your kitty fought off initial infection, or whether the infection has progressed into the bone marrow.  Cats with ‘latent infection’ and are not sickly may not show up positive on either test.

What do we do for sick, FeLV confirmed positive cats?  Because the disease is life-long, we try to keep cats from getting secondary infections.  This means keeping them indoors in a protected environment, where owners can also keep watch over daily activities (eating, drinking, using the litter box, playing) and observe any changes that could indicate a change in the health of the kitty.  Regular exams with your veterinarian (every 6 months or so) help to detect secondary issues early on.  Regular bloodwork and deworming can help prevent problems as well.

What is the typical lifespan for an FeLV-positive cat?  A cat with a latent infection that isn’t showing signs of illness can live a normal lifespan.  Kitties that are actively sick with positive ELISA and IFA tests can live for 1-3 years with good care.

Can we prevent infection?  Testing strays before adopting them into your household can help identify disease before exposing other naïve cats to FeLV.  Keeping known FeLV viremic cats away from other naïve cats is key as well.  There are several FeLV vaccines on the market that do have efficacy when given yearly as boosters.  They are not 100% effective but are a very good idea for cats that spend time outside or around known FeLV-positive cats.

Fear of Fireworks and Storms in West Central Indiana

It’s that time again! Thunderstorms and fireworks affect many pets. Check out some tips that may help you and your furry friend to have a happy holiday weekend.

West Central Veterinary Services

The Fourth of July Holiday.  It’s a wonderful time of year, with warm weather and picnics and time spent outside with loved ones.  Often we celebrate our country’s independence with a BANG!  (literally).  For some of us, that’s thrilling.  For those of us that have furry friends that are frightened by things that go ‘boom’ and ‘flash’, it can be a tough season of the year.

Compounding the problem, the holiday falls right in the middle of severe thunderstorm season, which can mean several months of anxiety management at home.

To some extent, all dogs and cats have some fear of anything that falls out of a normal routine, especially loud noises. Dog hiding under bed Some pets are overly fearful, to the point where we as their humans need to intervene.

This fear can exhibit itself in many different ways.  These can include hiding, pacing, whining, drooling, howling, trembling, destruction of things in the…

Cat Bite Wounds

Spring is here, and at the veterinary clinic that means more than wonderfully warm weather.  Here it also means lambs and baby calves and cat bite wounds.

Everyone seems to emerge from the winter cold and quiet and here we are with cats that are mating and fighting with one another.  Hence the cat bites.

WCVS website 354

Happy kitty with no cat bites. 

So what is the typical presentation to us at the veterinary clinic?

 

  1.  The owner sees his/her furry kitty friend engage in a squall with another kitty.
  2. (Or, alternatively, the kitty friend is let outside for the day and shows up in the evening with a limp or just doesn’t feel good).
  3. Kitty doesn’t have any energy.
  4. Kitty doesn’t want to eat or drink.
  5. Kitty may have a swollen leg or may be lame on one leg.  (Often it resembles a broken leg).

Typically, these cats are running fevers, with 104 degrees F and higher pretty common.  They can be dehydrated and extremely painful.

When cats bite, they inject bacteria deep into the muscle tissue with their long canine teeth.  These bacteria fester over the next few days, during which time the skin may even heal over, trapping infection inside the muscle.

These infections require prescription oral antibiotics to heal properly.  Sometimes an x-ray is required to rule out a fractured leg.  Sometimes the skin over the wound dies and falls away, leaving an open wound that is managed with bandaging and fly repellent.  Sometimes pain relief is required, or even hospitalization to rehydrate a very sick cat with IV fluids and start with injectable antibiotics.

Another thing to think about is the transmission of other diseases by cat bites, such as feline leukemia, FIV, and FIP.  This discussion is an important one to have with your veterinarian, especially if your cat is outdoors.

Every case is different, but now you know the basics of what to look for with cat bites!

FAQ: How Often Should I Deworm My Pet?

We get this question a lot, especially for routine yearly exams for our patients.  How often should we be deworming our pets?  The answer is:  it depends!  Let’s discuss.

First of all, we need to understand which ‘worms’ we are talking about.  What enemies are we fighting?  After all, nobody wants these guys in our pets and in our homes.

hookworm_color

I mean, seriously.  This hookworm is scary.

  1. Hookworms.  Primarily a concern in dogs, this worm has eggs that are shed by infected animals and live in the soil, waiting for your furry friend to gobble them up as they nose around in your yard.  These worms are also passed from mother to baby through the placenta or milk.  They live in the intestines and suck blood, which over time causes low red blood cell counts (anemia), weight loss, diarrhea, lethargy and death.
  2. Roundworms. Seen in both dogs and cats, this worm looks like spaghetti when shed out with stool.  Often puppies and kittens get them from mom through the placenta, so we see babies shedding worms even as early as 6 and 8 weeks old.  They primarily live in the small intestine and cause weight loss, poor hair coats, intestinal blockage and rarely can cause nerve and eye disease.  This worm can be spread to people, especially children, making it a top priority to keep dogs dewormed in homes with families.
  3. Whipworms.  Primarily a concern in dogs, this worm lives in the large intestine and is shed in the stool.  Furry friends ingest the worm eggs and they grow into the adult worm stage in the intestine.  Causes diarrhea, dehydration, blood loss, weight loss, lethargy and death.
  4. Tapeworms.   Our furry friends can pick up tapeworms from fleas, soil and from hunting rodents in the backyard.  We see little bitty segments of worms in the stool that look like rice.  These are actually only small pieces of the actual worm, which is roughly 6 inches long and are attached by a mouth part to the inside of the intestinal wall.  To get rid of these, a critter needs to be de-wormed and de-flea’d too.
  5. Heartworms.  Both cats and dogs can get heartworms, which as adults live in the lungs and heart.  They are spread through mosquitoes.  The insects take a blood meal from an infected critter, thereby ingesting the immature form of the worm (called a microfilaria).  Then the mosquito moves down the road and takes another blood meal from an uninfected animal, where the microfilaria break through the skin and get into the bloodstream of the newly infected dog or cat.  Over several months, the microfilaria grow into 6 inch long spaghetti-like worms that settle into the large blood vessels of the lungs and cause disease.  Signs of disease include weight loss, shortness of breath, coughing and death.

 

Ok, take a minute and catch your breath.  Like, wow.  These things are not only gross, but they spread disease (they could even spread disease to you!).

Now that we know what we’re fighting, get your battle gear on.  We’re going into battle against these buggers.

First things first.  We need to figure out if your furry friend actually is carrying any of these parasites.  It’s important to note that these worms don’t shed in the feces every time the dog or cat stools.  In fact, it’s common for there to only be eggs shed in the stool, which are microscopic and unable to be seen with the human eye.  Bottom line:  Your furry friend could be infected without you even seeing any sign of worms. 

So let’s do a simple test.  Look at a fresh stool sample under the microscope and see if we find any worm eggs.  This is a 15 minute test called a “fecal flotation”  that can be done here in the vet clinic.  Once we know what we’re dealing with, we can pick a dewormer that best suits your pet’s situation.

Keep in mind, heartworms are the worms on the list that cannot be simply killed by an oral dewormer.  Heartworms need a more complex treatment involving injections and hospitalization.

Like most battles, the best defense is a good offense when it comes to parasites.  That’s why we really like these monthly chewable pills that we give that can kill intestinal parasites AND kill heartworm microfilaria, too.  So every month your pet is protected from these nasty critters.  An alternative way to approach them is to give a heartworm prevention injection (Proheart 6) every 6 months, and check your pet’s stool with a fecal flotation at the same time, deworming if necessary.

We would love for you to call and come into the clinic!  We can test your pet for parasites and come up with the best plan for your family to prevent infection and disease.

Heartworm Prevention Options in 2016

Every year seems to bring another new product to the veterinary world for prevention of heartworm disease in our beloved pets.  And of course we still have a few products that we’ve had for years that are familiar.

Heartworms are worms that are spread by mosquitos from pet to pet.  They literally live in the heart and lungs and cause disease and death in affected animals.  For a recap on heartworm disease, check out our previous blog “Heartworms:  What’s the Deal?”

Another great website for learning about this disease is Veterinary Partner.com.  To view this site, click here for dogs and here for cats.

We have known about this devastating disease for decades now and have some effective drugs that protect and prevent these worms from growing inside your furry friend’s body.  As we have previously discussed, an ounce of prevention is worth a pound of cure when it comes to this disease.  Dog treatment is difficult on a dog’s body, it’s expensive, and takes at least 4-6 months to complete.  Cats often cannot be treated for the worms themselves, and get supportive care only.

Prevention is the key.  With a number of products on the market, we can find a product that fits into your lifestyle and your budget and also protects your furry friend.

Think about the cost of treating a dog that is infested with worms, or the cost of getting fleas out of your house!

Another plus:  many heartworm prevention pills also deworm your pet at the same time.  There are even some that kill fleas, too!  All in one pill dose.  It’s amazing, truly.

Let’s discuss the products that we are going to keep on hand here at WCVS during the coming year, 2016.

  • Proheart 6 :
    • An injectable product that prevents heartworm disease for 6 months.  The injection is given in the clinic. This product is very convenient for many owners.
    • Remember that it does not deworm for intestinal parasites, so many owners will bring in stool samples every 6 months when it is time for injection and deworm if necessary.
  • Interceptor Plus:
    • A monthly chicken-flavored chewable tablet that prevents heartworm disease for 30 days.
    • This chew kills heartworm microfilaria, roundworms, hookworms, whipworms and tapeworms.
  • Trifexis:
    • A monthly chewable tablet that prevents heartworm disease for 30 days.
    • This tablet kills heartworm microfilaria, roundworms, hookworms, whipworms and fleas.
    • Prevents flea infestations in the home.

Remember:  With any heartworm prevention product, we need to have a negative heartworm blood test before giving any kind of prevention.  This requires a small blood sample from your pet and an in-house test.  This is simple to do and results are quick!
