My cat Beau has always been thin. I've always wondered if there was something wrong but because he eats I just figured he was just thin. If you stroke his back you can feel his spine and if you grasp his waist you can feel his hip bones. You cant see his ribs but you can feel them if you run your fingers across his rib cage. I'm wondering if he has diabetes. I tried to weigh him but the scale shuts down over 11 pounds so with a three pound tare for his cage he's at least eight pounds. I'm going to bring him to the vet Tuesday. He's not always at the water bowl and he does not urinate frequently. I have been able to see his second eyelids from time to time but I figured his eyes were always bugging out of his head since he was a kitten ans this seemed normal for his facial structure. He always seems to want to bury his food. Any thoughts?
