Minigriff stats and write-up?

[Driddle]

I'm looking for a miniature griffon write-up to serve as a basis for an improved familiar (ala pseudodragon). Instead of a lion crossed with an eagle, I see this li'l guy as a calico house cat with blue jay wings ...

Anyway. Anyone seen one around these parts? Numbers? Art?

There's a creature called a Tressym, IIRC. It's a Forgotten Realms thing, and they're basically housecats with wings. I think they've been updated to 3.0/3.5 stats, but I'm not sure where...
