Cat Deworming

There are a variety of worms that cats can get from the environment and from what they eat. Fortunately, we have tools to diagnose intestinal parasites, as well as treat them. We would love to help you ensure that your cat and your home is worm free. Ask us about the best deworming schedule for your cat(s).

What are some types of parasites found in cats?

The most common parasites that we see in cats are roundworms and tapeworms. A cat can become infected with roundworms from contaminated soil or surfaces, or kittens can become infected through the mother’s milk. Tapeworms require a host for a cat to become infected. They can become infected with these parasites by eating either a rodent or a flea. Other parasites that we can see in cats include coccidia, giardia, and hookworms. Cats become infected with these parasites from a contaminated environment as well.

If my cat has worms, what symptoms should I look for?

Some of the main symptoms seen if your cat has worms are diarrhea, bloating, lethargy, anorexia, and vomiting. It is more commonly seen in kittens and outdoor cats but can sometimes be seen in indoor cats as well. Other things that may be seen if your cat has worms are actual adult worms in the feces and ‘sesame seed’ looking things on the fur by your cat’s anus.

Are worms dangerous to humans?

Some of the worms that cats can get can be passed to humans. Roundworms are the most common parasite that we see, which is one of the parasites that humans can contract. When transmitted to humans, the roundworm larvae migrate to the eye, which if untreated can cause permanent loss of vision. This parasite can also migrate to the lungs, which causes coughing and asthma-like symptoms. How do humans get roundworms? Humans can become infected after accidentally ingesting roundworm eggs in soil or other contaminated surfaces. Roundworms mainly affect children and compromised individuals.

What is the deworming schedule?

A cat’s deworming schedule will vary depending on the life stage of the cat and the environment it lives in. Ideally, a kitten should be dewormed every two weeks from 2-8 weeks of age, then monthly until six months. Once an adult, 2-4 times yearly, depending on the cat’s exposure to parasites. An outdoor cat may even require more.

Are there any side effects from deworming medication?

We seldom see any side effects with our dewormers. What we see more often is adult worms coming out in the stool. This can be a little disturbing for some people but be comforted to know that the dewormer is doing what it is designed to do.

Being a Veterinary Technician

October was Veterinary Technician Month, though many of us feel that it could be a year-round celebration.

Dear Clients,


At Manitou Animal Hospital our primary goal is to care for your beloved pets. By extension, this means keeping you as a pet parent healthy as well. Many of you have already recently visited the hospital and have personally experienced the additional safety procedures we have put in place to ensure the well-being of you and your pets using our “closed waiting room” policy.

Our "closed waiting room" policy:

  1. When you arrive in the parking lot, please remain outside the hospital and use your cell phone to call 519-893-1360. We will take a history of your pet's health and discuss any concerns.
  2. A staff member will then meet you outside to bring your pet into the hospital for an examination.
    We ask that you remain in the parking lot and keep your phone turned on.
  3. The Veterinarian will call you once the physical exam is complete to discuss the recommended treatment plan.
  4. We encourage credit card over the phone as the preferred payment method. We can also accept e-transfer.
  5. A staff member will bring your pet and any medications back outside to you.

During the coming months and as long as COVID-19 continues to circulate in our community we at Manitou will continue to offer our services using these enhanced safety procedures, including the curbside and closed waiting room service model. For the health and safety of everyone, we will not be able to have you accompany your pet(s) into the clinic for procedures at this time. We unfortunately would just not be able to meet proper physical distancing requirements and ensure your safety and our team's.

We typically have a significant number of clients [100+] visit our clinic daily whether it be for medication, food or for a visit with the veterinarian or vet technician. Space in the front room and the exam rooms is very small, a well documented factor for increased risk of COVID transmission. If everyone were to come inside our clinic, even with masks on, it would significantly increase the risk of COVID exposure to each client entering the clinic as well as our staff. We are simply not willing to risk the health of you, your family and our staff. We know that with continued effort we will get through this together. We sincerely appreciate your patience and help in working with us during these challenging times.

Until then, we promise to give each and every one of your pets the very best care and a ton of hugs and kisses when they are in for a visit. We always treat them as if they were one of our own and look forward to seeing them!
