Other things to consider
Size and cover are two other things to keep in mind. Most playpens are suitable for small- to medium-sized canines. They are also used for rabbits and guinea pigs. Other pets, such as bearded dragons and tortoises, cannot adapt to common playpen designs and can be prone to physical injuries.
As for cover, the open type is great for pets who do not jump. Humans can easily play with them or use the pen as a temporary holding place. Covered designs, on the other hand, are great for those who tend to jump high enough to escape the pen, such as cats and rabbits.
