If a cat has worms, several signs may hint at an infestation, though only a vet can confirm and prescribe proper treatment. Here’s what to look for and what to do. What to watch for

• Visible worms or worm segments: You might spot worms in the stool, in the fur around the anus, in bedding, or in vomit. Some worm types shed segments that look like tiny grains of rice or white spaghetti-like pieces.

• Gastrointestinal changes: Diarrhea (sometimes with mucus or blood), vomiting, or frequent soft stools can accompany many worm infections.

• Appetite and weight changes: Pets may eat more yet lose weight or have a sudden change in appetite. This can occur with several worm types as they compete for nutrients.

• Abdominal appearance and coat: A pot-bellied look (especially in kittens) or a dull coat can be associated with heavier worm loads.

• Secondary signs: Lethargy, coughing or difficulty breathing (if worms migrate to the lungs), pale gums (in some worm types), or general signs of poor health.

What to do if you suspect worms

• Check a stool sample: If possible, collect a fresh fecal sample and bring it to the veterinarian for a fecal flotation test or other diagnostic tests. This helps identify the type of worm and the appropriate treatment.

• Visit your veterinarian: A vet can confirm infection, determine the best deworming medicine, and check for potential transmission to people or other pets. Some worms require specific medications or multiple doses.

• Preventive care: Regular veterinary check-ups and preventive deworming according to your vet’s guidance help reduce recurrence. Keeping a clean environment, managing litter box hygiene, and preventing access to intermediate hosts (like rodents) also lowers risk.

Important notes

• Not all signs are caused by worms; other parasites or health conditions can produce similar symptoms. A professional exam is essential for accurate diagnosis and safe treatment.

• Some worm segments (like tapeworms) are more visible around the anus or in bedding, while others may be seen in stool or vomit. Observing exact appearance can guide conversations with the veterinarian.
