Merlin is a male tuxedo cat. He is two years old. I noticed a couple of weeks ago that he would be taking long pee breaks in his litter box. I found it odd but didn't really grow concern about it. But lately he has been really irritable, hissing and growling at me. He is now peeing in our bathtub and on our bed. And today he just threw up on my daughter's bed. He is eating but not as much and it seems that he is not drinking any fluids. Does anyone know what this sounds like?
