Best cat name ...a Russian blue called Kilmouski.

Coo! Opportunity to lecture...

Lots of people think "felix" is latin for cat.

"Felix" is Latin for "lucky".

Further:
"Felis", often applied to cats, means thief.
Makes you wonder about "felis"itations doesn't it?

"Catulus" sounds cat-friendly too, it means "puppy".

Latin for "cat" is "cat". Though, I guess, cattus catulus would be a kitten.

The cat in the pic would be "felis cattus", the kind that are not so into newspapers and dissapproving looks at humans are "felis _silvestrus_ cattus".

Hence: Felix and Sylvester as cat names.
