Bird heater with perch. Birds can snuggle up when it's cold, allowing them to regulate their own body temperature. * Mom's body temperature setting (approx. 40°C) * 1 detachable perch * Approximate electricity cost per hour: ¥0.14 Body size (mm) Heater: W130 x D15 x H190mm Perch: φ18 x Length 120mm I kept it at home without using it because I replaced the cage with an acrylic case. Part of the fastener is discolored, please check the 7th photo. There is no box or instruction manual. Please refrain from purchasing if you have any concerns. Photos 4-6 are substitutes. Thank you.
