She woke me up a lot last night and didn't seem to rest well like she usually does. Well at 6 this morning she woke me and I brought her to potty. She pooped normal and we went back to bed. About 30 minutes later I noticed that she was trembling like she was cold. She already had her night gown on so I wrapped her in a blanket. A few minutes later she jumped up and needed to potty again. This time it was much more soft than normal and some was yellowish color. (sorry to be so graphic) I cleaned her up and wrapped her back in her blanket because she was still trembling. Her tummy is making all sorts of grumbling sounds. I just gave her a bit of Nutrical because she hadn't eaten since last night and won't even take her favorite treats. With the long weekend our vet is closed. What should I do? Any ideas what this could be? She did steal a piece of a Cheeto that fell on the floor yesterday but it was small and I'm not sure it would be enough to upset her tummy this bad. Right now she is sleeping on my lap in her blanket...
