Poor kitty. Most definitely Lzzy should be seen by a vet. 4-5 days of both vomiting and diarrhea without medications started to help with this is bound to cause him to become severely dehydrated and malnourished. He also needs a fecal exam and potentially bloodwork to determine what the underlying cause of his iillness is, so that he can receive proper treatment. At the very least the vet can prescribe medication to stop the vomiting and antibiotics +/- probiotics for the diarrhea, after making sure no parasites are in the stool that would also require a dewormer. Best wishes with Lzzy and I hope he can return to normal soon. Take care.

    I would recomend taking him into the vet. A kitten can become dehydrated quickly from vomiting and diarrhea and since it has been a couple of days it does not appear to be self limiting. He may have parasites, viral or bacterial infection. The vet will likely recomend a feline leukemia test and fecal parasite test to start. I hope he's better soon.

    I would recommend taking your kitten in to the vet to be evaluated since the vomiting and diarrhea was unable to resolve on its own. You may also want to bring a fecal sample to your appointment so they can check for intestinal parasites. Your kitten will probably need a dewormer, some antibiotics and maybe nausea medication to get her feeling better.
