Using this K&H Thermo - Kitty Playhouse is easy. Just place it in a spot your cat likes, plug it in, and let your cat enjoy. When your cat's scratching pad gets worn out, simply take it out and put in a new one (you'll need to buy the refill pads separately). As for maintenance, keep it clean by vacuuming or wiping it down occasionally. Make sure to check the power cord regularly for any signs of damage. Also, don't place it in a damp or wet area. And remember, it has a one - year limited warranty, so if there are any issues, reach out to the seller.
