Super Pet releases Treat Play-n-Learn, a bird cage that makes bonding, training, cleaning and interacting easy, the company reports. The cages are designed to stimulate pet birds while providing them with a safe and secure place to live, according to the manufacturer. The expandable top provides pets with an area outside the cage for playing and bonding, while the large front door offers easy access to the bird and doubles as a landing perch, the company adds. The cage is available in sizes designed for parakeets (13.5 in. x 11 in. x 18 in.) and cockatiels (16 in. x 16 in. x 23 in.) The open play top raises the cage height to 22 in. and 28 in., respectively.
