Designed for larger cats weighing 18 to 30 lbs, this oversized 52-inch wooden exercise wheel offers a roomy 46.85-inch inner diameter and 11-inch-wide track so big cats have space to fully stretch out while running. The solid wood frame and widened 13.31-inch base keep the wheel steady during energetic play, and the narrow 0.2-inch running gap helps protect paws. A built-in silent wheel and noise-reducing base holes keep the workout quiet, even during nighttime zoomies. Rated to hold 190 to 220 lbs, the wheel itself weighs 49.6 lbs for a solid, stable build. It comes with pre-installed screws and wheel hardware, gloves, a screwdriver, and a cat teaser wand to help train your cat to use it. The looped carpet track mat detaches for simple cleaning, and a locking mechanism lets the wheel stay fixed in place so it can double as a resting perch between play sessions.
