I posted a thread about this like a week ago or so regarding London. We've been to the vet a couple times and still don't know what's up. She has colitis but what is causing it is the question. She's already lost 2 lbs and she's tiny so that's a lot for her. She used to be a chubby muffin, now she's skinny and I'm scared. They spent 2 nights at the vet and they hydrated her and watched her. They said she didn't throw up so that was good and her poops seemed to be going back to normal but then they sent her home with another round of metronidazole and I don't see it working. She eats like a bird now, it's so hard to get her to eat, if he wants anything at all. and tries to poop every 5 minutes but all comes out are tiny pieces or drops of poop, no big solid normal chunks

I don't know what to do! They did x rays, blood work.. All came out normal . I was worried it was cancer or something cuz of the weight loss but they said her blood results / enzymes came back normal so idk what to do!! She's really really little so I'm worried sick that she doesn't want to eat. :..( she's 7 years old btw, please help me.. I have no idea what it could be. And she really doesn't get into anything so I don't think she ate anything. She's really picky
