Yesterday I noticed quite by chance, on a few of the pink pad areas of the hind paw of Oliver some tiny white rough spots, just like sort of callus you get on the sole of the foot sometimes, like after walking around with an ill fitted shoe.
I donĀ“t think he is experiencing any discomfort, he was totally nonchalant while I was examining (he became fidgety after a while but that was just the sign of the end of his patience...), but I thought it a bit strange, he is a 100% housecat and it is not like he roams around on a rough terrain, is it common, or even possible for a cat like him to get a callus on a paw? If not, is it some kind of a skin disorder which needs to be treated?
