Ok, everything seems to have been resolved with the @hivewatchers account.
Lack of Circulation!
I find my blood does not flow the way it used to. Also the books in the library are all kind of just stuck there. And the air isn't moving. There is, everywhere, a lack of circulation!
What kind of hair should a cat have to improve its circulation. Do you know why I'm think about that when it has nothing to do with the subject? Because the subject of my cat looms large for me always and constantly. She's sick. She's been sick for 3 months now. Maybe longer. She seems fine, but the fluid is building up in her chest cavity, and for several thousands of dollars now, we've been taking her to vets to both try to get it to stop and to drain it. We don't want her to die, but we don't have an infinite amount of money, and we've already spent more than I think someone who was thinking responsibly about money would. It's on credit cards with zero percent interest for a year, so the reckoning has been pushed down the line.
But she frolics and cuddles and purrs and is just so happy with us, and in theory, if we had the money to do it, we could keep her happy and comfortable and like-normal for a long time. It seems awful to make any financial decision that will result in death or suffering if you have any other choice.
