Is my kitten sick, she is a little bloated?

They all, including mama cat probably need deworming. Stomachs can be distended in kittens from worms/parasites. Especially strays. If you arent taking them to the vet for this, try an over the counter dewormer that says strongid or nemex. It should cover roundworms and hookworms. Make sure they are old enough for it. Kittens can have plenty of canned food. Dry has nothing to do with developing their teeth. The adult teeth will calcify and come at 4 to 7 months. But if they are eating dry make sure it is for a kitten. They are smaller pieces (you can always crush it) and the kittens need the extra fat. Mama should be weaning them off. Anyway, the bloated kitty, worms or not may be having a little trouble digesting at the same pace or eats more and takes longer to digest. You should be able to take them to the vet for an exam and deworming at a group or litter rate. Call around and just ask. Kittens also can have giardia which IS transferable to humans. You should take a couple poop samples to the vet! This young they arent going to make you do the vaccines yet.
