That's so sweet.
I've yet to catch any of my cats asleep in Nathan's crib. They all jumped in it to check it out when we first got it, but I haven't seen them in it since. We have a cat bed under the crib and one of my cats likes to nap in there while Nathan is asleep in the crib.
It's funny, I used to keep a basket of receiving blankets on the dresser and I would constantly find the blankets in the cat bed under the crib. Anything I left on the dresser (Nathan's pajamas, a sweater, sweat pants, anything) would end up that cat bed. I finally found out which cat was doing it when I caught him carrying a blanket in his mouth out into the living room.
