Male buff (somewhat tabby) kitten.
Missing right rear leg (essentially, the hock). Gets around OK but somewhat stilted.
Very friendly. Wants to be picked up and purrs alot, desperate for attention (when we're near, meows alot from his crate and "rubs" the crate where he is staying in the barn).
Sorry for poor pix quality - last-minute cell-phone camera shot.
Should've mentioned they are about 2-3 mos old, by the looks of them.
