We bought Poggles a 4.5 inch curved PVC tube. At first, it was hard to convince him it was a good idea.
He went into the tube, but he didn't get it.
He just sat there and looked around.
He even gave me his miserable face!
But then he discovered that it was fun to turn around in it.
He could go out one side.
Finally, he found some clothes to burrow under, made himself a nest, and settled down for a good, long nap. What a fun day!
