Hope Yumi gets better soon. Cuddles was an indoor cat and got abcesses from time-to-time. Turns out it was from spider bites. (Yes, we have spiders in Alaska). She'd lick them as hard as she could to get them to burst. Her hair was so thick and some times we didn't even know she had an abcess until after it burst or else we would have taken her to the vet. Hope Yumi is on the mend.
