I have two kittens at home. One of them, not sure which one, seems to have thrown up twice over night. At first I only saw one puddle, and thought it's soft stool. But upon closer inspection, I'm pretty sure it was vomit, especially because it was somewhat "grainy" and smelled kind of neutral. I later discovered a second puddle, but it was completely clear. I searched some pictures on google, but all "clear" puddles seem to either be yellow-ish or foamy. What I found was really transparent/clear, almost like water. As I'm a new cat owner, I'm honestly not really sure. Is it possible the second puddle is actually pee? My cats never peed on the floor (thank God), so I'm not sure what it would smell like. It smelled slightly acidic, so I thought it might be stomach fluid?
As I said, I don't know which of the cats had to vomit, but they're both behaving normally, so I'm assuming as long as there is no more vomiting, I don't need to be alarmed?
Thanks.
