I mean in Krazy Kat, the animals are gender-ambiguous and there's only one cat in love with a mouse. Here it seems to be a strange and arbitrary rule that cats love mice, which makes the unlikely unrequited romance that made the comics so compelling much less remarkable / poetic. Also, fuck you!
You can never make a cartoon approaching the comic, but I will admit that Krazy's voice is werra werra similar to how I imagined it talking in the comic when I read it as a kid.
