You have me nearly pegged on housecats, but "hate" is a strong word. I merely have no love for them. I still think the rendition of the cat is horrible, but not as bad as the 1989 that features a Persian cat: ...or the semi "artistic" renderings of 1993 and 1995: ...or the rotten flesh zombie cat on the 1994: The 1990 alley cat one is better, at least it look lifelike, but still kinda plain: Some of the newer ones with kittens are cute, but what's up with the 2001 and the 2004 being virtually the same design:
Interesting observation on these, and I think you're right. Not very good. The zombie cat - if silver - could compliment the Zombucks.
