As he had advaced FIP. The thing was that he was abused and took me a long time to catch him. But the vet said that he was carrying the FIP for a long time, so catching him earlier wouldnt have helped. Of course I threw out all the dishes and washed the porch.So that Nervous and other cats wont be infected. And Nugget has gone to be tested , I will find out today.Please pray that he hasnt caught it. It was sad today knowing that Gem was not going to be there but at least his suffering is over. And now he can be healthy and play with his fellow Cat Angels at the Rainbow Bridge. RIP Gem.
