Vision bird homes have many revolutionary design features that set it apart from traditional bird cages. Most cages come with pull-out drawers that fail to do a good job at collecting bird waste and create maintenance headaches as a result. Vision's unique no-drawer design simplifies cage cleaning-simply detach the cage portion and empty the contents of the base into the waste bin. The result is less time-consuming, messy cleanups associated with bird keeping, leaving you more time to enjoy your pet. Vision's deep base can handle multiple types of litter, while raised ridges inside the base provide air circulation and help prevent mildew. The bird homes also allow non-invasive, exterior access to seed/water cups, reducing stress to birds during maintenance. In addition, multi-grip perches promote circulation and help prevent foot problems. The knock-down cages are easy to assemble with a five minute quick, click-snap assembly.
