We use a lot of pens and cage tops to keep guinea pigs confined at outdoor events. This one is sturdy and solid, and although it's made for dogs, it's ideal for multiple guinea pigs. Word of caution, never leave guinea pigs unattended outside. It only takes a second for a hawk or other predator to snatch them up. That's why a covered pen is best and supervision a must!

Pros: keeps guinea pigs penned

Cons: no cover to it

Very good to have these at shelters for puppies to play with each other. Also, if you have any rescues or strays dropped to you like I have.

Pros: room to play and not be alone

Cons: no

My sister has one of these. When she takes her dog to a dog event. The pen goes along to give her dog room to wonder freely.

Pros: mobel pen

Cons: none

I love these playpens! They are great to put rabbits and guinea pigs in so they can get some fresh air and eat grass!
