The other thing is, check her stool for any sign of worms. Vets automatically worm kittens
on their first visit, assuming all kittens
have roundworms. Maybe they do and maybe they don't, but the meds used to worm a kitten for roundworms are considered safe so they just do it as a matter of course. Roundworm medication can be bought online or at the pet store, just be sure of the doses if you want to worm your baby, since she's still so young. Don't give her anything else, though.
