I use tile as well, and I still have to clip Kalec's nails, though not very often. One of my jobs is at a dog grooming salon, so I'm very used to trimming nails. I just use a pair of cat nail clippers and clip a small bit off the nails so they're not sharp. Be very careful of the quick though as sometimes it can actually be further up than what it appears to be on the outside of the nail.
