Please Help...cat not eating

My Smokey, a blue russian I believe, is a 5 year old male that I took in as a stray about 9 months ago. He has always eaten well: dry science diet food (sensitive stomach formula) with a little bit moist food and gravy. But now he hasn't eaten in two days and I am very worried. He has also been sleeping in the bathroom which he has never done before. Any thoughts?

Please get your cat to the vet. Not eating for more than two days can lead to some serious health problems in a cat.

Yes, and he's off hiding. Not good.

I hope the vet can diagnose and treat the little guy easily. Hugs to you both...

Has your kitty been tested for leukemia? Not trying to scare you, but I take in FeLV+ kitties and the behavior you are describing is the behavior of a leakemia kitty when the disease has kicked in, please get to a vet ASAP!

thanks guys
I was planning to take him to the vet in the next day or so if things don't get better. A friend said he may just have a bad hairball and another suggested maybe just some sort of cat flu...is there such a thing? Anyways, I have the day off tomorrow, so I will take him then...unless y'all think I need to go NOW?

I would go now

I 2nd that .... you need to go now ....... please keep us update .......

Thanks all.

FYI, $300 later and the blood tests were inconclusive. He had a fever and was dehydrated so they kept him overnight and got him on antibiotics and some water and then sent him home. He seems much better.

never thought I would cry over a cat

That's great to hear that he is doing better. Sending lots of get well vibes

I'm glad he's doing better!!

Glad to hear this seemed to only be a fever. My cat had similar problems but she was badly constipated. An enema did the trick! But she had not eaten much in three days...it's a good thing I didn't wait any longer to get her treated by a vet.
