A playpen is a secure place for your bunny to roam and where you can interact with them without fear of them running away.
I think a playpen is essential for young bunny owners.
We’ve owned a number of types of pens over the years, and the one below is the last one we purchased. We got this about two years ago, and it’s handled the use and weather just fine (my daughter isn’t always real good about getting it put away).
It’s water and pee resistant, which means a pee puddle can easily be cleaned up before it gets to the carpet below.
It has a removeable top and bottom, so you can give your bun access to the grass while you are then to watch him, or put the bottom on to protect your carpet or hardwood floors.
We put the top on if we’re going to leave a bunny outside (in a secure fenced yard) in the playpen while we run inside for a bit.
