Food for thought
I had a cat a few years ago get FIP Feline Infectious Peritonitis (FIP)
Normally not a cat person but this cat was great. He acted more like a dog as he would always run to great you when you came home and shadowed your every move. Anyway it started off by not eating, snotty nose, and not acting normal. Then he had a seizure that was caused by a high fever that we didn't know about. The vet tired the normal antibiotics and such to no avail. Finally agreed to some testing that came to around $600. They found lesions on a few organs and recommend surgery for the tune a $1000+ which wasn't an option for us. I did a lot of researching and stumbled across FIP. I called the vet and he agreed that it was likely the case and there wasn't much we could do. Long story short the cat would have some good days and some bad days. Then all of a sudden he started to act like his normal self for a few days in a row which was great. However things took turn down hill fast within a couple more days he started to have issues walking and limping real bad and then started to loose control of bodily functions. We put him down right away cause it was easy to tell that he was suffering. All of the happened in less than a months time.
Keep a close eye on your cat. I think ours started to act normal a few days before he died because he gave up the fight. People in my family that are in the medical field seem to think that they have seen terminally ill people do the same once they give up. They seem to perk up right be for they die. Not saying this is the case for you but sometimes what seems to be a common cold or sickness turns out to be something much more severe.
