My daughters cat has been vomiting what can we give him for an upset belly?

What is he coughing up?

Sometimes my cat regurgitates her food, and if that is the case, don't be alarmed. I think it is something they all do. She is an outdoor cat as well, and quite a good hunter (she leaves me treats from time to time).

The cat may have hairballs, she may be trying to expel it from her body and causing her to vomit. I know it sounds gross but check in it and see what you find. If this is the case you can prevent some hairballs by brushing daily, buying hairball formula cat food, or hair ball remedy in a tube(can be found in the pet food asile at most grocery stores). I have found as my cats get older this is more of a problem. If the cat is vomiting profusely then it may need to see a vet, there maybe something serious going on. Good luck :)
