I have a black cat, when we first got her we were told she was male and at that time we were really in to the television series 24 so we called her Almeida, by the time we found out she was female it was too late to change it haha.
Oh that's so cute! I actually had the reverse happen - my sister thought the black (tuxedo/ snowshoe) kitten she found was a girl because 'she' has nipples. It wasn't until I brought "Muffin" to the vet a week later, in a pink kitten carrier designed to look like a large purse, that we found out Muffin was a boy.
So we changed his name to "Brutus."
that's so cool you have all those rats! i volunteer at the Humane society and i love playing with the rats...and freaking people out when they ride on my shoulder XD
do your cats try to get them? heheh
