Still can’t get a hold of my vet.
I came up with the conclusion that perhaps the fleece is actually abrasive to his feet, despite how nice and plush it feels. I read this on a site today that any sort of carpet/towels, etc can be abrasive. Tonight I went to HomeDepot with the intention of buying the rubber floor that K&K uses (at least I’m pretty sure it’s the same stuff). But it is really soft rubber with grooves in it that I suspect he would chew plus it would cost me a lot and I’m not sure if it will help his feet or not. So I settled on some foam interlocking mats (discussed in the habitat forums). They are shock absorbing and have little grooves and nudges but we flipped them over to the smooth back so he won’t be as tempted to chew.
I’m concerned that he might chew these, despite all my efforts, but am sort of at a last resort here. I interlocked them as snug as can be so there’s not much groove for him to grab with his teeth the floor is longer than his condo so he can’t grab any of the ends. I left one of his smaller fleece throws.
I really hope to see some improvement (and hear from my vet) very soon.
The good news is that, as I type, he is out for run time and doing some insane binky/zoom combos so he’s obviously not tender there.
