IIRC, shippind weight was 70 pounds, which given my back problems is a ton.
Getting it from the end of my driveway where UPS left the box to the house wasn't fun. I opened the box halfway down the driveway and carried the pieces to the house separately.
It's on wheels though, so it's pretty easy to move around the house or take to the front porch for hosing down. But yea, far from portable.
I also don't like that the floor isn't solid. He has gotten his foot caught in the floor a couple times. I'm now putting a blanket in there when I'm home to supervise. I don't trust him yet with a blanket when he's home alone.
As for biting the bars? He hasn't been bad about it. He learned quite quickly that those bars aren't gonna yield to his teeth. But then again, he never escaped from anything more difficult than cheap plastic, so when it wasn't easy he quit trying.
