Rabbits need to be dewormed, and we just need timed deworming at the doctor's instruction. The parasites are much smaller than the parasites inside and outside the cat and dog body. After all, they're vegetarian, as long as we're healthy when we're raising them.

Hint:
Although the rabbits look clean, they're very hygienic, and we have to clean up when we raise them. Last one. Next one.
