I've done a little research & they sound like they might be a good option, but I'm slightly hestitant about a couple of things.
Believe me, if there is a will, my cat will find a way.
Kitty sometimes scratches a little raw place on himself (pea size). We keep his nails (front & back) trimmed, as he is an inside cat only.
We also use Revolution. He definately doesn't have fleas, mites, or a skin condition. He's just a scratcher.
If one of these caps get chewed off or fall off naturally, how harmful would it be if swallowed?
If by some chance the glue becomes exposed, is it toxic?
