I have a 6 ish month old foster kitten. She was spayed about 3 weeks ago. She has been dewormed several times. She has constant runny poop. Not just runny, liquid. The soonest I can get her into the vet is Christmas Eve. She is not lethargic, she's eating, drinking, and playing just fine. Any thoughts? Right now I have her confined to the spare bedroom with her brother, because she poops on her back legs and it gets everywhere, but I'm going to keep them in there for a little while after she goes to the vet just so I can monitor her poop and see if theres any changes.
