My cat has worms in poop. Is her dewormer working for tapeworms?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 6 years and 8 months old

My cat is taking dewormer and when she had a bowel movement this morning, I saw these worms in her poop. I attached a picture. What type of worm is it? I want to make sure the dewormer I'm giving her will get rid of it. The wormer is pyrantel pamoate 50ml. She had been vomiting and lost a little weight and was a little less active. Could worms cause these symptoms? Thank you

From the picture these look to be tapeworm segments. Often you will see them dried on the rear end too. Pyrantel is a great broad spectrum dewormer, but it doesn’t kill tapeworm. Droncit ( praziquantel) kills tapeworm. I always recommend a full fecal exam looking for microscopic eggs as animals who have parasites often have more than one kind. Tapeworm can cause gastrointestinal signs if she has a high enough worm burden. Best of luck and I hope she improves soon! Thank you for using Pet Coach.
