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 the most common of the parasitic worms found inside a cat (or dog). Almost all cats become infected with them at some time in their lives, usually as kittens. Roundworms may be contracted in different ways, making them easy to spread and hard to control. Your cat may take in (ingest) infective roundworm eggs from the area where it lives or by eating mice or other small animals (hosts) carrying young worms (larvae).
