My 10 week old kitten threw up Sat twice, once was after eating, with the hard food still whole (not xhewed)the second time was on empty stomach about an hour later. I feed him Orijen hard food, and Blue wilderness kitten for soft. So I stopped the hard food to see if that was why. Sunday he wouldn't eat, he just licked at his soft food, and drank a little bit of water. He ended up vomiting up yellow bile a few times that day. So Monday I switched back to his hard food and took away to soft figuring maybe that was it. I cut up his hard food so he wouldn't swallow it whole. He ate a few bites that morning, and when I got home a few hours later, he threw it back up when he woke up for napping. I called his bet, and got an immediate appt. They examined him, tested for feline leukemia, and said he may helave a sensitive stomach, so to try switching the soft food to a special GI kind. When we got home, I tried giving him some and he just sniffed at it, pretended to bury it, and walked away. I tried mixing it with his hard food later that evening, and he only licked at it, but wouldn't eat it.. Today, he has only licked it a few times as well, then walks away. His last BM was yesterday around 5pm, it was softer than usual, which is likely due to the eating pattern recently. And has peed twice in 24 hours. So far no vomiting today, but I'm worried about his not eating. His vet said I can come back in tomorrow if it xonti yes, but will cost around $300 for blood and work and xrays and such, which I can't exactly afford but will of nessisary.
