My kitten is throwing up undigested food and has pink diarrhea. Why?

Hi, My kitten started to vomit about 3 days ago. He eats ( does have appetite) and about an hr later he throws it back up undigested. The food looks exactly like it did in the food bowl. Also yesterday he started to have pink coloured diarrhea with an awful smell . The vet told me today that it's worms or hairball ( he was dewormed up to date before this started). He got dewormer today again (about 12 hrs ago) yet he's still throwing up. Is this normal or what else could be causing this?

I am sorry Sock is not feeling well. This much vomiting is not normal. I would be concerned about a foreign body causing obstruction, infection or even possible coccidia. I would recommend taking Socks to the vet for additional testing like an x-ray of the abdomen and even possible blood work. the concern is dehydration and weight loss with the vomiting. I hope that helps
