Hey Fuzzy…just brainstorming:
The occasional declawed cat shows up in those shelters & you could specify that you can only take in declawed kitties. I did some fostering several years back & brought home my first two guests, one of which had been declawed by his original owner. Over time there were a number of cats listed as being declawed & likely the same is true up in your neck of the woods….so no threat to your new chairs-to-be.
And while it’s true that there’s no getting away from cat litter, they’ve come a long, long way with said litter. The new-ish clumping litter is (to me) sort of miraculous & i guarantee you there’s no cat pee smell in my hacienda….(i’ve got a superb sniffer lol). If I had a mobility issue i would probably use a somewhat smaller litter box along with the litter box liners they have now so i could just reach in daily & remove the whole shebang & be done with it versus going the scoop route.
Oh & i’m plenty willing to brainstorm your other etc etc’s if you’d care to elaborate
