Cat threw up after new food. Should I switch back to his old wet food?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 4 years old

Hi, I recently switched my cats food. He was eating wet food before and I gave him a new brand/flavour of wet food. He threw up today twice, the first time it was a hairball but right after eating later on in the day he threw up again. Is this because of switching food too fast or is it the food itself? Also should I go back to the previous brand/type of food?

Yes, the vomiting can be from switching the food. I always say "don't mess with success" so if the previous diet was working I would go back to that. Whatever is in the new food may not agree with him. If you go back to the other food and he continues to vomit then he definitely needs to be seen by your vet. I hope this helps. Best wishes to you and Zander!
