What Worms Do Cats Get?
Cats can harbor several types of intestinal parasites. Roundworms (Toxocara cati) are the most common — kittens often acquire them from their mother's milk, while adult cats are infected by hunting prey. Tapeworms (Dipylidium caninum, Taenia) are transmitted by swallowing infected fleas or rodents. Hookworms (Ancylostoma) are less common but can cause severe anemia. Toxoplasma gondii, while not technically a worm, is a protozoan that cats shed in feces and that can infect humans — particularly concerning for pregnant women.
Many infected cats show no obvious symptoms, especially with light burdens. Heavy infections cause pot-bellied appearance in kittens, poor coat condition, weight loss despite eating, diarrhea, and occasionally worms visible in stool or vomit.
First 3 Steps to Take at Home
- Check the stool and anal area: Look for rice-grain-sized white segments near the tail or anus (tapeworm segments) or spaghetti-like worms in stool (roundworms). Take a photo for your vet.
- Bring a stool sample to the vet: A fecal flotation test identifies which parasites are present and guides the correct deworming product — different drugs target different parasites.
- Start a deworming schedule: Kittens should be dewormed every 2 weeks until 12 weeks of age, then monthly until 6 months. Adults should be dewormed every 1–3 months depending on lifestyle (outdoor vs. indoor).
When to Go to the Vet Immediately
- Kitten with distended abdomen, diarrhea, or weakness — heavy worm burdens can be life-threatening in kittens
- Cat with pale gums (anemia from hookworm feeding)
- Cat vomiting live worms
- Suspected toxoplasmosis in a household with pregnant women or immunocompromised individuals
Follow-Up Care Checklist
- Follow the deworming schedule prescribed for your cat's lifestyle and risk level
- Clean the litter box daily — many parasite eggs become infective within 24–48 hours
- Control fleas (tapeworm vector) as part of the overall parasite prevention strategy
- Consider combination broad-spectrum parasite products that cover roundworms, tapeworms, and fleas in one monthly dose

Summary for Your Clinic Visit
Bring a fresh fecal sample, describe any symptoms, note the cat's lifestyle (indoor/outdoor, hunter), and tell your vet the last time the cat was dewormed and with what product.
