PetPal Gear Score

How much vertical room and how many climbing levels the cage gives an arboreal glider, which uses height far more than floor area. The 69-inch three-level Yaheetech and 60-inch Madagascar score highest; a compact starter bundle scores lower. Single-tier cages are marked down unless the height is exceptional, because a glider needs structure to climb, not just an empty tall box.

Whether the bar spacing is verified at or under the half-inch glider-safety line. The Yaheetech's verified 3/8-inch spacing scores highest; the Mcage and Prevue score well at a verified half inch, though half an inch sits at the upper limit rather than under it. Cages whose listings do not publish a spacing figure cannot be verified on paper and are scored on their glider-purpose marketing instead, not a number we invented.

Material durability and whether a glider can gnaw through any part of the cage. All-metal, chew-proof builds like the Mcage and stainless steel like the Brisbane rate highly; any plastic panel a glider can chew is a mark against a cage. Rust resistance and coating quality count here too, since gliders live in humid, frequently-cleaned enclosures.

How easy the cage is to clean and reach into without risking an escape: slide-out trays and grates, multiple access doors, and rolling stands. The Yaheetech's ten doors and slide-out tray and the Mcage's grate-and-tray system rate well. Easy access matters more with gliders than many pets because they are fast, escape-prone, and most active at night when you least want to open a whole cage.

Price relative to honest height, verified safety, and build — not the lowest sticker. The Mcage scores highest on raw value as a tall, chew-proof, verified-spacing cage for the least money, while the glider-branded bundles cost more for the specialist name. Value is judged against what an arboreal glider actually needs, so paying extra for a brand name without extra height or tighter bars is not scored as a bargain.
