I noticed that my cat has suddenly been having hiccups, and is vomiting. The vomiting is very unusual for him. When he ate a raisin, and we gave him stuff to make him vomit, but he wouldn't, so this is very worrying. We don't really have money to take him to the vet incase it's nothing. So, can anyone help me/him? What is the cause of his vomiting and hiccups? Is it dangerous? He does not have scheduled feeding times, and he is 3 years old.
