Both of our cats are prey-driven, so fast-moving stuff is key (laser dot, teaser-under-circle-skirt machine). The youngest is also a student of geometry, in that she’s a marvel at calculating the angles needed to clamber upon every possible surface.
Today’s skill: pulling herself under the desk on her side, slithering up the back of the drawer, and clambering inside. Rustling from the drawer tipped us off, and surprise - kitty inside!
