Although my cats get along beautifully, I doubt we'll have a pile o' all them anytime soon. This is the closest I've gotten with three of four - Be.au, Spenc.er, and Sylv.ie.
I have an online friend who is on cam in chat. She knows how I love piles o' and she will train her cam to her bed, which often features a couple dobies, a min pin, and a kid all wallowing together... a live action pile o'! I just giggle at the wonder of it. She even has two week old kittens now, but they're not ripe for anything but piles o' bitties right now.
