I'm lucky in that hubby, after all these many decades, has finally fallen in love with the cats, too. He's much more agile than I am, despite being older than me, and takes care of those. Anything that causes the cats fear, I deal with. My little Japanese Bobtail went through most of her life with few, and finally no, teeth, as well... like your 8-year-old. It never stopped her or hindered her in any way, but then I made sure everything she got was chopped finely.. minced, in fact. And she shared my Lactaid with me as a night time treat. She was over 20 when I lost her a few months ago. Wish we were close enough to help out... I'd probably take a couple of your older cats.. including toothless. Or at least find someway to help out. We who have rescued critters I consider a special breed; we need to stick together as much as possible. I'll keep you in my thoughts with regards not only the cats, but to your own medical issues, as well. May life smile upon you, Spin... and relieve some of the burdens from your shoulders.
