Using the M - PETS Warmo Self - Heating Mat is super easy. Just place it where your pet likes to rest, and they'll enjoy the cozy warmth right away. There's no need to plug it in as it works by reflecting your pet's body heat. When it comes to cleaning, simply remove the plush cover and toss it in the washing machine. As for maintenance, make sure to check the non - slip bottom regularly to ensure it's still effective. Avoid sharp objects near the mat to prevent any damage to the layers. If you notice any wear and tear, it might be time to replace the mat for your pet's continued comfort.
