I cant believe I'm writing about another sudden problem with my cat, but any help will be great. My cat that's 4/5 years old has been excessively drooling for potentially a few hours as I only noticed it just. Hes an outdoor cat and when he came home i noticed he had some stuff around his mouth, but thought nothing of it. Went to see him and he had been sleeping, but he seemed off to me for some reason. My assumption is that's hes either in pain or tired or possibly both. He is making really strange noises with his jaw, almost like grinding, but it entirely. Its difficult to explain. I checked his mouth and he let me which is what got me thinking that something is upsetting him. I couldnt see anything wrong with his teeth or gums or mouth, but then again I'm no vetenerian. He moved out of his box onto the carpet and moved again, which is when I noticed a patch, about the size of a small cookie, of what looked like he had drooled. There was nothing wrong with him beforehand other than the fact that he had lost a bit of weight, but we put that down to him roaming around all night for days in end (he does come home for food). I tried to give him some water and he tried but then started making those jas noises. Please help, the vets doesnt open for a few hours.
