I'm new here I came here to find some more info as to the reason my cat of 14 yrs passed away on friday. We had to put him down because he was suffering from a tumor the size of a grapefruit in his stomach. He deteriorated very quick and we could not watch him suffer any longer. He was my best friend and he will be missed greatly. I was just wondering if anyone else had a kitty pass from the same thing and if so what was the cause? The vet said it just happens but there has to be a reason that it did.
