My cat is long since departed but she had a few quirks I very fondly remember.

Whenever she was excited, usually (but not always) about dinner, her tail would be in the shape of a question mark and it would rapidly vibrate as she walked up to you.

Whenever I came home, she would watch me through the window, then run to the door and dramatically flop in front of me. This was the cue that I should position my foot so here back feet could push against it as leverage while I slapped her hard ass just above her tail like she was a bongo.

Her way of waking you up for breakfast was to stand right on your chest, put her nose almost on your lips, close enough for the finest of her whiskers to tickle you as she purred as loudly as possible.

When she slept she would make grumbling noises as she turned over or repositioned. Sometimes it sounded like she was a tired old man finally getting comfortable after a long day. Sometimes it was more like the sound of someone stretching as they yawn, but with their mouth closed. Sometimes it was more of a grunt, as though she were inconvenienced by gravity. You'd randomly hear it from under whatever blanket she was hiding under.

When she wanted to remind you that you were hers, she'd walk up to your leg, headbutt it, but then stand on your foot with her back feet while leaning against you, with her tail curled around your leg. It didn't count if she wasn't standing on you, she'd reposition until it was right.

I miss her a lot, but I'm grateful I had so many years with her. You could often hear her purring clear across the room. Sometimes I would rest my ear against her chest while I petted her, just to flood my senses with only purring and soft fur. I can still hear it.
