I have a 4 year old domestic indoor cat she is usually a very lively cat about 5 days started showing signs of being very lethargic, we haven't seen her go to the food or water dish she wont get off the bed at all. She just lays there looking very sad. There are no running eyes or nose no drooling, just very lethargic. I've been giving her droppers of water so that she at least is getting that. She is urinating normally no change in color or smell. She gets very aggitated if you attempt to pick her up like she is in pain. I feel so helpless, I don't know what to do to help her, I really can't afford a Vet visit any idea on what may be wrong?
