The directors at the Institute have noticed that the study subjects have formidable  built-in weapons, some more impressive than others. Here Zippy displays her lovely claws which she uses to knead her favorite blankie. She has never clawed either the Director of Input nor the Director of Output in our passions of petting. We can’t say the same about lap kitty Velvet who will not allow us to touch her belly or her paws.

Zippy uses her impressive sharpies only for kneading her blankie.

Here’s the tattoo Velvet administered when the Director of Input absent-mindedly touched the sacred belly.

Velvet’s response to an accidental belly touch. Looks bad but was superficial.
