I'm selling this because I bought it for my cat but no longer need it. It's a USB-powered small pet seat heater. It maintains a temperature of approximately 28°C, providing a comfortable warmth for your pet. Since it's low-temperature, there's no risk of burns, and it can be used for extended periods. It comes with a cord cover for safety. Size: 40cm I opened it, but I haven't used it even once. It has been stored at home, so please consider purchasing only if you understand this.
