Q. Cat 14 yoa not eating, extreme weight loss in last week, heavy breathing, shaking head, weak extreme anti social, not drinking, heavy urination
A. I recommend getting your cat in to see your vet as soon as possible for an exam and labwork. The symptoms you describe can be attributed to a number of disorders such as heart or pulmonary disease, liver or kidney problems, among other things. Comprehensive bloodwork is your best chance at finding out what is going on with your cat and deciding how best to treat his condition.
