Amazon Basics 24" Round Dog Playpen with Door - 6-Panel Beige Pet Exercise Pen for Indoor & Outdoor Use - Perfect for Puppies, Small Dogs, and Training

Good light-weight portable fence. The sections snap together firmly, but not easily. I find that the best way to do it is to lie them flat and use your foot to snap them together. It can be done by hand, but to do the bottom of the fence is a bit tough. I also find that the fence cannot "fold up" once it is put together. In other words, you can't just fold them up in one easy-to-carry stack. You have to unsnap the sections to do that, or get help to move the whole thing. This is a bit inconvienent when moving the fence about, which my thin metal fences do easily. Still, this is decent, lightweight, and sturdy fence and I like it. The one caveat is that I bought this for bunnies, and a 5 month old Japanese Harlequin was able to squeeze almost completely through it. Almost... Her head, shoulders, and abdomen made it through. Her hips and rear legs did not. (See photo.) And with her hind end off the ground, she had no more traction to "pull" herself through. Had she hung there for any length of time it could have killed her. To get her out, I had to cut a slat loose with a hack saw and lift her out. She wasn't injured in any way, just caught. The fence was easy to epoxy back together though. And, to be fair, the bunny getting caught isn't the fence's fault in any way. It's just not appropriate for small animals (or determined young bunnies) who may get caught in it.That being said, for adult rabbits I've had no problems with it. They certainly won't be able to knock it over, but if you put a large container in there they may want to try to hop over it. I've been using inside, and in the yard, and overall I've liked it. I'm considering buying another one.
