He was raised with 3 cats. The cats hate him. Hate, Hate, Hate. Guido doesn't give a rats ass and is always pushing his luck. Guido loses every fight with any of the 3 cats BUT.... he seems to like losing. He loves to agitate them until they mentally break and go after him with 'death' on their minds.
Here Guido is about to get whacked upside the whiskers by Chowder... the cat that hates him the most. You'll notice that Guido is standing on the back of a sofa. He pretty much lives up there. Sleeps up there. Never falls off. Raised with 3 cats I'm convinced he now thinks he's a cat. The aftermath of this photo is:
He got whacked then proceeded to hit warp speed around the house losing control several times and slamming into 2 chairs, 3 or 4 walls, a recliner, and me. And oh yeah, it's grooming time.
