I was cuddling Toff last night and noticed his paw pads are really rough , running my finger over them was like going over a cheese grater

I had a quick look online and some people seem to think snow and water/hard surfaces can cause this condition
he isnt in any discomfort , and he's not biting or licking them but is there anything I can do to help smooth them out ... like applying some kind of oil or cream ? (any ideas which ones if thats the case)
