The girls have either been grabbing each other's seat when one gets up or trying to share Penny's little bed which results in overflow so hubby and I picked up a new one yesterday at Wal-mart. The girls love it! Penny liked it so much that she slept in it last night and didn't come to bed until 6 a.m.!
And, to make things better, it is made from recycled materials.
I couldn't find the dog one online, but here's a pic of the cat one and
a link with more info. It was $24.99. We got one that has shades of light brown with a red trim around the edge. Super cute!
