Well, I got the pen. Was 55 bucks more at PetSmart but I had to get it for the weekend. I am going to see how he likes it, which he hasn't so far so I left him in the crate this morning instead of the pen, but I really need it for Sunday. I will be returning it next week and may order the one on Amazon since it's is SO cheap!
Jimmy just digs and digs at the walls. I imagine his little nails may get caught in it. I would hate to have to cart around a metal pen...I may try the child one from Toys R US too...hmmm
