My cat used to overeat. Lately, he has lost his appetite. Whereas he'd jump at ant sound of food, now he just sits there. We put him in front of the bowl, but he won't eat. He's been losing weight, and has been having trouble breathing. He's had this cough since we had him, but lately he's been coughing a lot more. It used to end in throwing up a hairball or something, but nothing has been coming up.
We took him to the vet today, and they checked him. But whatever is causing it, they need to do expensive tests to find out. We can't afford all the tests and such. Would anyone have any ideas on what we should do?
