In each of these is a sleepy rat! I guess they're just.... hanging around! In the pink and yellow one is Tarzan, one of the babies. Behind him in the yellow and purple one is his brother, Tchaikovsky.
The big guys are in the front, Merlijn is in the green one (sleeping on top of his head) and my darling Chuck is in the black and grey one. That leaves Noah! I didn't have a sputnik for him so he found a place in a different plastic house on the bottom of the cage, far far away from his brothers.
My poopies have a good life with me :D
