So this morning marks the 2nd occasion where one of my 3 cats has thrown up what looks like coffee grounds. The first time I was out of town and returned to find it. I thought maybe it was fluke and didn’t give it a second thought. This morning I saw it again and decided to find out why it looked different (usually they throw up whole pieces of food from eating too fast or hair balls). I’m going to call their vet asap today but do I take all 3 or try to discern who the vomit is from? Also what are the other symptoms I should be looking out for (Paranoid me googled it and saw the word cancer and slammed the computer shut).
