Can we have the white fat cat? (and a black one too, please!)

I remember seeing this little guy in a photo (like his icon) on a minion site, with no direction as to how to get it. I guess it's in the game files but not IN the game yet.

And it has been like that for years now. I'm thinking this white fat cat went the way of the Spriggan hat and was forgotten until someone brought it to the dev's attention.

Well I'm bringing fat cat back! Would love to see the white one, and even a black one in game.

Can we please look forward to it? :)
