Sadly, my littlest little one didn't have it in her to overcome her ailment. She died in my arms at the vet's at about 5:55 this evening. She wasn't getting any better, and when I got there she seemed like she was pretty much done. I am very sad, but putting her to sleep was the right thing, I think. She's in a better place now, I hope...one where her legs work again, and there are fields of catnip and plentiful small rodents that are easy to catch and good to eat, and about a zillion secondhand couches lying around so that she can pee wherever she pleases and not get yelled at.
