So this morning my kitten felt a bit uncomfortable and vomited something that looked clear. (Only a but). Then later after some time it vomited again. This time it looked like its poop. So we visited the nearest vet (which, by the way, had really good google reviews) and he gave us an injection for the kitty. Hes eight weeks old. He advised us to give him gaestrointensinal wet food in portions. So wr did that. After the afternoon passed away and night came we noticed watery greenish/brown stool stuck to his butt. Then after cleaning it he had more attatched to it, except it was brown instead of green. And each time we gave it wet food it was really hungry and it ate everything. Now its sleeping and we're reconsidering our vet choices. Im really worried and i dont know what to do...
