Tapeworms in Cats and Dogs

Animals Affected

Dogs, cats, puppies, and kittens.


Tapeworms are parasites of dogs and cats.   They live in the intestines and, although they rarely cause clinical symptoms or disease in pets, they rob their hosts of nutrients.  Tapeworms are aesthetically unpleasant.

The most common type of tapeworm is spread by fleas. Pets contract this species of tapeworm when they swallow fleas in the process of grooming.  Other tapeworms are spread through improperly prepared food.

Eosinophilic Granulomas (Rodent Ulcers) in Cats

Animals Affected



Eosinophilic granulomas are ulcers or sores that develop on the lips and in the mouth of cats.  They occur when the cat’s immune system misdirects its activities and attacks the cat’s mouth.

The syndrome is painful.   Severe eosinophilic granulomas can become infected or can be disfiguring.

With treatment, most eosinophilic granulomas can be managed.  However, cats often develop many ulcers over their lives, and the syndrome can be a chronic problem.
