Playtop bird cages are popular because people want their pets to be happy and well adjusted. Birds absolutely need time out of their cage every day. Playtop bird cages will allow your pet to perch or play on the cages highest point where they can enjoy a "bird's eye view".
Play top bird cages come in a variety of styles. Avian Adventures has a clever design in their lift-off play top bird cages. You can remove it from the top of the bird cage and set on a table in another room. The idea (and itís a good one) is to provide your bird a different environment to play in, to keep things fresh and interesting for your pet. Remember, a bored bird will likely start to cause trouble to drum up excitement on their own.
