My first cat was named Pi (like the number), my second Romeo. If I got a new cat, I don't know what I'd name them yet... I name cats (and everything else) very much on impulse/vibes.
I don't remember exactly why she was Pi; I think it was because she was a calico tabby and looked a bit like s'mores, but I also wanted something kind of nerdy. I was really into Gravity Falls and I thought about naming her "Ford" I think too. With Romeo, when he was a kitten he was REALLY affectionate, so I named him that since he was "a little lover". Now he's more standoffish and aggressive, but that rather suits "Romeo" doesn't it...

My general naming convention for animals is wanting something that sounds a little "unique"/isn't "Oreo" but also isn't necessarily trying too hard. I think I stray away from names that indicate their animal-ness. It should be a weird enough name that you'd be a little surprised for it to be your human friend, but it would be plausible. My dad has taken in a cat who was named "Mr. Whiskers"; I would not name a cat that unless it would be very funny. But it is cute.
