【High-Quality Materials】Using rust-resistant epoxy resin paint, it has excellent corrosion resistance and wear resistance, allowing you to use it for a long time. 【1-Tier, 2-Tier Type Adjustable】One tier for one kitten, and as they grow, or if the family grows, or if you welcome a new cat, you can expand to two or three tiers and enjoy arranging it. 【Convenient Casters】It comes with a total of 4 casters. Two of them have stoppers, so you can lock the cage to prevent it from moving during use. With casters, it's easy to move when cleaning! 【Knob-Type Doors】Doors are attached to all tiers, making it easy to put in and take out cats and items. Easy opening and closing by simply turning the lock, and your cat can't open it from the inside, so you can rest assured. 【Hammock and Wide Shelves Available】Your cute cat can relax and unwind. Also, it's easy to take out of the cage and easy to clean. 【Large Doors】The top and bottom doors open wide, making it easy to care for your cat. The entrances are wide, making it easy to put in and take out toys and for your cat to enter and exit. *For 3-tier types, the top is a bit high, so we recommend using the 2-tier type for the top. 【Easy Cleaning】Sand, food, and small items fall through the holes in the floorboard into the pull-out tray below, so you only need to remove the tray and throw it in the trash without having to gather scattered sand! Also, the floorboard can be removed and washed if it gets dirty. 【A Safe Place for Your Cat】Using a cage is recommended to prevent injuries and troubles for small cats left alone. Also, creating a place where they can rest safely can reduce stress during disasters. A spacious space that is convenient for multiple cat owners.
