Also my first pet, so feel free to give me some tips. How to keep her from going under the car all the time, for example.
Make sure she gets a lot of new experiences, toys, change up the treats every now and then. Animals without variety can easily get bored/depressed and it's such an easy thing to avoid. Before my crested gecko passed last year I had a big Tupperware bin that I filled with dirt, egg cartons, fake plants, rocks, logs, etc. and every now and then I'd release a bunch of bugs in it and let him go nuts. He was usually fed the pre-mixed fruit diet (mango banana was his favorite) so he always went bonkers in the goblin-dome. He also loved trying different mashed up fruit, so whenever I ate some fruit I'd mash up a bit and see if he liked it. One time I peeled a grape for him only for him to bite it and immediately drop it in the dirt. Ik this is a gecko I'm talking about, but the same principles apply to any animal and can really bring their personality out. A friend of mine has a nerf gun he shoots at his cat who goes nuts over it (he's very close to figuring out how to pull the trigger himself) Caveat to this is that cats can sometimes get temporary digestion issues if you switch up their normal food, so pick one and stick to it but treats are fine.
Also she looks like a long haired cat, so make sure you brush her. Matted fur can pinch the skin and be incredibly painful for them, and also a pain in the ass to remove since the skin can get caught up and cut if you try to shave/trim the mat. My mom's cat is a shorthair, but he's so fat he can't clean his back so we have to brush him often to avoid mats.
I'd go Mildred - follow my train of thought here.
The cat's eyes make it look scared. Therefore, it is a scaredy cat. Scaredy Cats is the name of a fun anarchist-run horror movie channel. Scaredy Cats the channel is run by Mildred.
