My 8 year old cat started vomiting hairballs on Wed and Thursday. He would eat a little white meat tuna, but then throw it up too. He wasn't eating his dry food at all. I took him to the vet on Friday and his blood tests came back fine and he doesn't have a fever. They gave him fluids Friday and Saturday are suggesting x-rays. He didn't throw up Sunday and seemed to keep at least a little tuna down. But he ate a little tuna this morning and a little later he threw up a hairball. He still won't touch his dry food. I'm giving him laxitone from the vet. Should I opt for the x-rays, or should I be a little more patient and see if it just because he's shedding and has hairballs? I'm not sure what to do.
