Nephthys (Neffy) spends an awful lot of time upside-down with curled feetsies

Classic cat trap. They lure you in with a fluffy belly and cute curled feetsies, then clamp down on your hand.

"Neff THIS!"

I have a friend whose cat is named something very similar.

The cat is very deaf, and occasionally makes an odd noise that sounds almost like a kindergarten human child.
