On our most recent trip to Ikea, Eric and I splurged on a play tent for Amos ($7.99). We were so excited and got it all set up, I even put some blankets and pillows in it to make it seem like a really cool hangout spot. Well, Amos took one look at it, and thought in his little head: "Hamster Ball!" He immediately threw himself into the sides of it, rolling all over the room. We laughed soo hard with him as he crashed into everything, and eventually ended up outside of the playroom.
Sadly, the fun is over, it didn't take long for Maggie to become his favorite target. We took the tent down, and we'll try it again when he's matured a little (so, like 25 years from now). Eh, it was fun while it lasted.
