How things can sneak up on you....
When the cat gets chemo, the expected pattern is that she'll be pretty okay that day, her appetite will drop for a couple of days, and then bounce back. And that happened, after her first does of chemo.
Not so much her second. Her appetite dropped, her intake bottomed out. We think she may have lost about 10% of her body weight. Yesterday, we put her on an additional anti-nausea medicine, and started discussing how long we'd allow this to go on, whether we'd but her through a third dose of chemo, and so on. Not a great time, that.
Last night, we went with friends to a dinner concert - good food and a mostly vocal group who do some great complex harmonies, doing really old folksongs (like, 1700s) about the holidays and the turning of the year. The last song was about new years, and went into folks no longer with us...
... and I was overwhelmed with a realization that my little furball was probably going to be among those who didn't make it to the new year. I'm sitting there, in the dark, song flirting with minor key, talking about endings, and it was... a bit much. I know a grown man crying in public is not generally acceptable behavior, but I didn't (and usually don't) care that much about what other people think to spend the energy to stop myself. My wife noticed. The couple we were with probably noticed. Others, I dunno, and screw them if they had a problem with it.
We came home, and found... the cat's food intake had increased significantly. So, maybe she'll make it? My wife takes her in for her third round of chemo tomorrow. I think there'll be a conversation with the oncologist.
