re: Vets / Cat owners.. My cat won't eat her food

If she doesn't eat tonight, I'd take her in tomorrow morning and not wait. Cats are notorious for hiding illness until they get too sick or past the point of no return. Mine had a raging UTI not long ago and the only way I noticed is when he finally started drinking a lot of water. Cats don't normally drink much, so I knew that was a bad sign of something, plus I feed wet food only with some water added to it. Had a diabetic cat and dry food was awful for her, so I switched them all to a low carb wet and got the diabetic cat off insulin and the others lost a little weight they needed to lose.

Could be a multitude of things. Could have a blockage esp if not pooping. Check for peeing, pooping, purring and preening.ETA: There are 5 p's. The 5th is playing. Check your litter box well.

Make sure you check for dehydration. Too much could lead to death, so any indication at all requires a vet visit as soon as possible. If you don't know how, here's a short video.
