My 13 yr old cat ain't eating and I'm extremely worried. He has been like this 2 or 3 weeks now, but has now deteriorated to him not eating at all. He's just had a stay at the vets where his blood was screened for the usual suspects, had an ultra sound, anti biotics, steroids and an appetite enhancer. Apparently he ate whilst at the vets but we've brought him home and he just isn't interested in food. The vet said there was nothing he could find wrong with him, and the last resort is an x-ray to see whether there is any problems with his head or something. Has anyone had any experience of this type of thing and can offer any advice?
