That cat would be Arhu, a reference to Divine Divinity. <ShamelessPlug>Which is now available practically for free at GOG.com</ShamelessPlug>
If you want more info, I'm sure MacBeth will come in here and write you a wall of text about it.
Thanks for that! Now I have something to go on, and proof that my assumption was as tenuous and wrong as I'd assumed.
I may yet give Divine Divinity a try: I tend to avoid isometric games (partly because I'm a lightweight first-/third-person addict, partly because older graphics give me migraines) but having seen a few screenshots it looks a lot better than I expected.
