If only Patch would be so compliant as to be a lap cat on call!

Hee hee - that'd be a skill, training cats to lap-warm on command!

Sometimes it's nice to have multiple cats. Mac is a total lap cat! He is always ready to 'assume the position' at a moment's notice. He loves to sleep on you, too. Kimba likes lap sitting when he's in the mood for it, which is fairly often. Ming is a love, gentle, affectionate, and sweet, but he DOESN'T do laps!

My girl cat sometimes doesn't even wait for me to get comfy before getting in my lap, or on my side, or on my legs. Wherever she can lay on me is fine with her! :D
