FELINE DISEASES

Feline Roundworms

The roundworms which effect cats are Toxocara cati and Toxascaris leonia. They are large worms 3-5 cm in length that live in the intestine. Adult female worms lay eggs which pass out in the cats faeces. These eggs then become infective larvae which can survive in the soil for many months. Cats become infected by eating or licking material contaminated with the larva, or more commonly by eating rodents, birds, and insects which have themselves become infected. Most of the larvae migrate through the body to the intestine where they grow to adult worms within a few weeks. Toxocara cati larva also have the ability to enter the mammary glands of a pregnant queen leading to infection of kittens either via the milk. For this reason it should be assumed all kittens will become infected with Toxocara cati.

Adult cats generally show few signs when infected with roundworms, however kittens can have a swollen abdomen, diarrhea, and vomiting (sometimes with worms) from as early as 3 weeks of age. Severe infections can completely block the intestine.

Diagnosis of roundworms is by identifying the worm eggs from samples of faeces using a microscope. A large range of effective worming treatments are available. Kittens should be treated every two weeks between 3 and 12 weeks of age. Adult cats are treated every three months.
