I'm skeptical..... although not trying to deny the experience behind the advice I have been given.
A very, very high grit sandpaper is not very abrasive. Not to say that it can't injure the pads on a hedgie.... but I personally wouldn't rule it out as an option with my limited (or maybe irrelevant) experience.
It must be considered that dogs kept indoors, in lawns, etc., commonly rip their pads on 'abrasive' surfaces. Naturally, this is less of a problem, but domesticated dogs are not conditioned to rough surfaces (in general). Even dogs that consistently run on gravel or hard asphalt rip their pads simply from natural injury.
Domesticated hedgehogs don't seem so different. They run on their pads, just like dogs. Their claws can become overgrown, despite lots of running on soft surfaces. And it seems they can rupture their pads when exposed to a rough running surface.
I'm wondering if a hedgehog that is slowly trained to a lower grit sand paper over time would benefit by having naturally trimmed nails.... or at least less frequent nail trimmings. Much the same as dogs that are allowed to run around on abrasive surfaces on a regular basis. Consider that a wild hedgehog wears down its nails enough in a natural environment to not rely on human care.
Is this thought process just ridiculous?
I'm not condoning taking an "easy out" when it comes to nail trimming. Simply considering a logical approach.
Feel free to give me any information regarding this topic. I'm simply looking for more info to benefit Crash.
