Ringworm is contagious. It spreads when you have skin-to-skin contact with a person or animal that has it. It can also spread when you share things like towels, clothing, or sports gear. You can also get ringworm by touching an infected dog or cat, although this form of ringworm is not common.
Roundworms are most commonly passed from adult mother cats to their kittens through the mammary glands. Kittens are at highest risk for health concerns related to roundworm infection, but adult cats can be infected by ingesting eggs from infected feces or intermediate hosts such as earthworms or rodents. Roundworm infection is called 'ascariasis' and generally does not produce symptoms in adult cats.
