Up to 85% of kittens may be infected with intestinal parasites. Roundworm, hookworm, whipworm, tapeworm, and giardia are the most widespread in the U.S. The roundworm (Toxocara cati) is most prevalent.
- If your indoor cat chases or kills mice, rats, or flies, he/she’s potentially exposed to roundworms.
- If you have indoor plants with potting soil, he/she’s potentially exposed.
- If you took your child to the playground today and walked through the sandbox, or if you were puttering in the garden, you may have brought home some eggs on your shoes.
- If your cat has roundworm eggs embedded in muscle tissue from a previous infection (or just from kittenhood!), they may hatch later in life or under periods of stress (like other illness, pregnancy, a new baby in the house, or a change in environment) and cause a variety of problems.
