I have two kittens one male one female. I woke up to my male kitten having vomited all over his crate and bed which also got on my female kitten. They are four months old. I noticed the vomit left was yellow and slimy so I looked it up and concluded it must be bile. I also found there was some thrown up food in another corner of the crate. So, that was at like 630 AM. Then around 7:30-8 he threw up again. More yellowish but this time bubbly looking stuff. No food but just yellowish clearish . I tried to give him water this whole time as well as a little food but he hasn’t been interested in either. Then again maybe at 845 he threw up again! I’m really worried. He’s not trembling or anything but he won’t eat or drink. And now that it’s 10AM, he hasn’t thrown up again thank god, but he still won’t eat or drink He is now sleeping. I left him water in his crate just the same. What could this be? The only thing I could think of that changed their environment drastically over the last week is: I got a new wet food from Purina for them. But other than that I had been feeding them instinct food. They’ve been eating it for several days now however so I’m not sure if that’s the issue. Also I took them both flea baths but only with dawn. This was also several days ago. Also my male kitten is very good aggressive I would say. He doesn’t get hostile but he’s always extremely excited for food and always eats a lot more than my female kitten. I’m a newbie so I’m really worried. Thanks !!!
