Not too long ago, we noticed that our growing kitten has been hanging nearly halfway out of her bed when she naps. She does not curl up in a ball like other cats when she sleeps, but rather she likes to stretch out. So we ended up getting her this new larger bed. It's actually a dog bed, but we won't tell her if you won't. This bed is more than enough room for our kitty to stretch out completely inside.
Well, it turns out that she just likes hanging over the edge . . .
