My parents have a Russian Blue look-a-like, Guy.
He is a domestic cat, but some guests say,
"Isn't he that Russian cat?"
My Mother just says "Yes."

Guy as a kitten.

Deep asleep with his face squished.

This is Kogin. Kogin looks like an American Shorthair.
Some guests say "Is he that American cat?"
My Mom just says "Yes."

Scrap often occurs between Guy and Kogin.

"Hey you! Wanna see who's the boss!?"

They are just pranking...
