Sphynx don't come in mini versions like many other pets, they're all quite large and strong. They might not be able to take your 5 year-old but they'll surely be able to defend you in the chance that an alley cat kicks in your front door at 2am. This plays very well with the ugly factor the Sphynx Cats have going on (have I mentioned this yet?), usually the ugliest kid in class is the toughest. Sphynx has got nothing more going for himself right?
