I am fostering a 6 month old kitten that has really bad gas, any ideas why?

I foster kittens so I understand your concern. You said the kitten has bad gas. Most likely it is diet. Does the shelter provide food for you? If so, it is the cheapest possible. I make my own kitten food from a raw food diet. You may just need to go and buy some more expensive pet food (pro plan is great). If your foster continues to have gas after a week, insist on a stool sample for coccidia. Coccidia produces the worst smelling poop and gas but is easily treated with Albon.

This can be faily common in kittens & does pass as they grow out of it. But remember not to compare one cat to another as all are so different & just because one has a type of food preference it does not mean the same would work for another. Ok it may have had a vets check but you need to register your kitten immediately with your local vets surgery & do your own. Never take someone's word as true as it may be, it's now your kitten & your responsibility. This is standard practice for any pet owner. A health check & questions such as yours can be dealt with & make it easier for future visits..Kittens & young cats pass through many phases as they quickly develop. At about one yr old they begin to settle more too..x

You might have the vet check a sample of her stool for worms. Worms can cause a kitten to have gas.

If she was on a different type of food before you got her and you are feeding her something different, it may have upset her stomach and is causing the gas. (Just a thought.)

Cute lol it's probably gonna go away soon.
