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.
Cats can get roundworms and through interaction with objects contaminated with their eggs. They can also catch ring worms by interacting with affected dogs. Even easier for cats to catch from dogs are tapeworms. This is because cats easily ingest fleas during grooming.
