Ling Jai has not been using his litter tray in his cage in the last couple of months it seems even when he is locked in over night, he urinates now on the surrounding carpet in his room and he tends to sit on his bum becuase of his week back legs when he goes and pretty much wets his bum and back legs with it, I'm going to have an overhall of his room this week to lay down wooden boards on the carpeted areas to prevent him urinating on it which worked a couple of years ago, I also suspect he tends not to choose to enter his cage now as his back makes it difficult so I am going to cut a larger opening so theres no obstruction, but the main concern is the wet bum and back legs scenario other than laying down saw dust in all possible urinating spots what more should I do as the urine will eventually scold his skin
