That is totally wild! A black lab showed up at my house last year and I let her stay (even though I'm not really a dog person). I don't think even she weighs 37 pounds. I've had cats all my life. So it's hard for me to fathom a "house cat" THAT big!
My last cat (R.I.P.) was a mellow dude - cool as he could be. The one before him was moody and had a nasty temper though. If he'd been as big as Pouncer, I'd be dead right now... several times over.
Sounds like he's a blast to have around though. I'll definitely check out that Youtube video!
Very, very cool. Thanks for sharing that.
