This just happened a few minutes ago, CC was retching and threw up a small quarter sized puddle of clear liquid. Immediately after, he sat down and wobbled and fell over backwards and took a second to get up again. Then he ran into the other room and vomited two more small amounts of liquid. Now he seems completely normal again. His abdomen doesn't seem to be causing him any discomfort as he let me palpitate all around his tummy. It's the falling over that concerns me most, what would cause that? My girlfriend will be home in 20 minutes, so I dont know if this is an emergency vet thing or a wait and see thing?
