Deworming Cats

Did you know that kittens can contract intestinal parasites (worms) by drinking milk from an infected mother? Cats can be infected through environmental sources such as ingesting contaminated feces or infected wildlife. The risk of being exposed to parasites including hookworms, roundworms, and tapeworms can depend on your location. These parasites will negatively impact the health of your cat! 

What does it look like when a cat has worms? 

Signs of worms in cats can include diarrhea, vomiting, and weight loss, however cats can be infected with worms and not show any symptoms. Younger kittens may have a potbellied appearance, look dull, or have poor growth. 

Is my cat at risk? 

If one or more of the following questions applies, your household is considered a ‘high-risk’ environment: 

1. Are there young children, immunocompromised, or pregnant individuals in the house or in frequent contact with the cat? 
2. Is your cat a service animal? 
3. Does your cat frequently come into contact with highly contaminated environments such as a boarding kennel? 
4. Does your cat have access to wildlife such as rodents, rabbits, birds, or carcasses of livestock? 
5. Does your cat eat raw meat or organs? 
6. Does your cat roam freely? 

How should I deworm my cat? 

Kittens are typically dewormed by the breeder at 2, 4, 6, and 8 weeks old. After bringing your kitten home at 8 weeks, deworm monthly until they are 6 months old. After 6 months and into adulthood, consult your veterinarian to create a deworming plan that best suits you and your cat. The Canadian Parasite Expert Panel recommends deworming 1-2x per year in low risk households and 3-4x per year in high-risk households. 

What is a fecal test? 

Fecal testing is an important part of how your veterinarian will determine the best deworming plan for your individual pet. Fecal exams can help detect new parasites, drug resistance, and reduce unnecessary use of medications. All cats older than 6 months should have at least 1-2 fecal tests per year. For high-risk households, at least 2 fecal tests should be performed per year. 

How can I reduce my risk? 

1. Practice frequent handwashing with soap and water after disposing of pet feces 
2. Keep pet defecation areas to a minimum 
3. Promptly dispose of fecal material 
4. Cover sandboxes when not in use and limit pet interaction with wild animals 
5. Visit your veterinarian for annual check-ups and to determine an appropriate deworming program best suited
