So I got this new kitten and have had him for maybe about two weeks. He is three months old and seems pretty healthy. He has had two loose stools today that are formed but kind of soft, but the thing that worries me is that he just threw up two tiny puddles of what looked like clearish liquid. I also put frontline on him today, so I'm not sure if there's something wrong with him or if he just accidentally ingested a little. He's on my lap now and purring and playing and seems energetic. I just moved him and his friend to my new apartment, so they are both a little scared and were hiding under the couch all day. Because of this he hasn't eaten since 12 PM. Do you guys think it is serious or am I just worrying too much? Does anyone have any idea what it could be?
