This picture is poorly edited...my apologies...but I think you can still get the gist.
Jeff apparently has the most comfortable lap in all of Christdom. There have been relatively minor scuffles (like one cat just continually nudging until the other cat jumps down) to all out warring factions vying for the treat of curling up and taking a nap in his lap.
I took this blurry picture a couple of evenings ago. This was a completely non-violent skirmish, thank goodness. What you see here is approximately 115 pounds of spoiled rotten beast all trying to sit in his lap at once. And that's not even all of them.
I should note: Simba won this round. He was sprawled all over Jeff's lap and half-oozed onto the couch. He was snoring about 7 minutes after this picture was taken.
