I went away for the weekend and when I came back I found some cat vomit on the floor. She seemed fine so I've been keeping an eye on her but she threw up again this morning, and now it is tinged pink. She recently started eating wet food but has been eating that for about 3 weeks now with no problems. Her energy level is fine and she's still interested in eating (even though I took her food away from her) and drinking. We also recently moved and the pipes in the apartment above us burst so I'm afraid that stress is causing her to throw up. She did not drink any of the liquid from the burst pipes because I locked her out of the one room that was affected. Thanks for any advice or suggestions as to what it might be!
