Borrow away my friend. I can see it now. Any bugs that find their way in there are likely toast, where little magic creatures will be ignored or be able to stay out of her way. Any innocent soul that makes their way in there will find a large fluff-ball willing to purr and cuddle as long as they're gentle.

And when Wraithvine needs cheering up over the centuries, he calls his tower and there's Lilbit, tail high and slightly curled at the tip, trotting over to him to rub along his legs and purr and sooth her person.
