Is this pen suitable for a bonded pair of regular sized rabbits?

I had a foster once that could jump a 36 inch pen like nobodys' business. I found I had to clothes pin a sheet over the top or he would be running the house and getting into all kinds of trouble within 5 minutes flat.The buns would absolutely be happier, more comfortable and safer indoors. Hey pets are for companionship and enjoyment and unless you live in your backyard you are not experiencing the true joy of having one right? I always fist lay down a remnant piece of linoleum under the pen to protect the floor then lay a sheet or fleecy down I just shake them out over the compost pile and throw them in the washer. ( keep an eye though as some love to chew them). Once upon a time Pier one used to sell those straw mats that come tied together with jute pretty cheaply and those were just ideal.
