Easy to assemble and store: It consists of six wooden boards, a cosy wool pad and a cat scratching board. Build the frame from the six boards according to the instructions and then place the wool pad and cat scratching board on top. It can be assembled or disassembled quickly and is small enough to store and transport easily after disassembly. Two-tier design: this two-in-one cat house has a hidden cube and a roofed recreation room. The lower layer has a fleece mat suitable for keeping warm in winter and can be removed in summer. The hollow design of the bottom is suitable for cooling in summer, so that the cat does not feel the heat in the enclosed space. Sturdy and sturdy construction: The panels are pieced together for extra sturdiness. You can also buy more than one for multi-layer assembly. Cats can play and jump on them without any safety problems. Ideal for families with many cats. Spacious and comfortable: The bottom compartment of the T-hideaway measures 17.7" x 11" x 11.8", ensuring a spacious and comfortable litter for cats of all ages. Note: The fleece mat may have some smell when first opened, which will disappear after a few hours of ventilation. You can buy with confidence and if you have any questions, please contact us, we can always accommodate all your requests. It does not matter even if the packaging has been opened.
