Who says math can’t be entertaining? Even the simplest equations can, like cat + shower. Of course, only one of my cats can actually clamber up the stairs to the shower and poke her face into the deluge. The other one has too much joint pain to even lick herself clean. Consequently her fur is all matted, which I used to find gross, but now I can sort of appreciate. It’s like having a pet mountain range. I would wager she spends a lot of her time lying awake, having to go to the bathroom but not wanting to get up until she can’t stand not to. She follows the course of the sun around the room she sleeps in all day, starting by the east wall in the morning, moving to a chair on the north side in the afternoon and finally to the couch by the fireplace in the southwest corner in the evening. And like the sun, she never reverses direction. All of her limbs are more or less vestigial at this point. It’s a bit sad, but on the other hand, now that she’s outsourced both the transporting of herself to her food bowl every day her insulin production to humankind, I think she has thrown her hat in all the way with civilization, and she acts like it.
