For two months my 1 year old cat has been dealing with erratic symptoms that subside then reappear. He has been lethargic, with on/off fever and in pain but still eats & uses the litter regularly. My main concern is the swelling. It first started w/ his right front arm then went away reappeared on his belly went away, reappeared on his back & his left arm & now head & eyelid is swollen. Yesterday I noticed his nose was a little runny and his eye had some discharge. He's been on Antibiotics, meds to stimulate his immune system and a meds for anemia. I've taken him to the vet and they are stumped. We've tested for Leukemia and HIV both neg and no one knows why he's having these symptoms and I cant afford to spend THOUSANDS of dollars for testing. PLEASE HELP!!! I've researched and have found nothing that is remotely close to all of his symptoms, especially the reoccurring then subsiding swelling in different parts of his body.
