Hey guys, I need some advice. My youngest kitty (3 1/2 years old) has this habit of scooting his behind on some of the carpety surfaces in my home for quite a few months, possibly more than a year, now. When I took him to the vet last time for his vaccine renewal, I mentioned this to him and asked if he could check my cat's anal glands, as it is often the cause of such behaviour. He did have a look and said they were fine, and thought nothing of the issue. Since then, my cat has kept doing this on a regular basis, and I'm sad for him if he has some degree of discomfort. I tried cleaning his behind thinking he might be annoyed by dried up poop back there, but minutes after, he was doing it again. Reading on the subject, it seems there could be other causes, such as parasites. I highly doubt that's the case as he's been dewormed as a kitten and has been living inside since. He also has none of the other common symptoms like soft stool, vomitting or lethargy. Another cause is allergies which I guess makes the most sense then, however he doesn't seem to be itchy anywhere else or constantly scratching. How do I go about determining what he is allergic to if he is?? Could it be the litter I use? Or possibly his food? Food would be one hell of an issue as he shares kibbles with my other cat that needs a specific diet to treat his CKD, and I cannot forego that.
