No, it sucked after a promising beginning. Oooooo, Thog gets supreme motivation from thinking Roy supposedly somehow hurting the dire wolf who was nowhere near the combat until being punched though the wall while Roy was grappling with Thog. I don't care if he dumped INT and WIS, no functioning creature is that stupid.
So take one ordinary house cat, add a belt of giant strength (or collar), and you'd get very powerful house cat who now can kill a 5th level PC. All Mr. Scruffy needs now is a Scruffy like tune when he does something awesome. And perhaps a hat.
