Out of our 4 birds, there is one that will not tolerate any noise after bedtime, so she sleeps in a bedroom that sometimes gets cold at night, I bought Louie this perch figured 'I would give it a try" . Luckily it resembles the previous perch in her cage, once on it and feeling the heat she is hooked, If I dare put her to bed and do not plug it in she screams until I do. Now I do not worry about her little feet being cold. She actually wants to go to bed at night since I brought this. I highly recommend it. By the way Louie is a Nanday Conure.
