My cat loves a stroke and he lifts his bum in the air when I stroke him normally. \r\n\r\nJust give him a good back scratch now, and noticed he is straining his bum slightly and there\u2019s something yellow in there, like a small ball or button (so not stringy like a worm)\r\n\r\nNot that I stare at his bum a lot, but I do check from time to time to make sure he\u2019s not sore if he\u2019s been overgrooming for example, and I\u2019ve never seen this at all. \r\n\r\nGoogle tells me it might be an anal gland, is it normal to see it when he\u2019s lifting his bum up? You can\u2019t see it normally, just when he \u2018pushes\u2019 his back up if that makes sense. \r\n\r\nHe seems fine generally.
