Review on Medium Snuggle Sack Bird Nest by Prevue Pet Products - 2-1/2-Inch Opening, Colors Vary by Amber Adams

Be careful if your birds are destructive, there can be many strands in the inner lower part which can get tangled and damage the belt. This happened to our lovebird, and it ended tragically. she got her leg so tangled she broke it and we had to put her down. That being said, I think the company should use a better, less destructible material, at least on the inside. The rest of the cottage itself is good. But if you do get one, just make sure to replace it if you notice any damage and avoid the heartache we went through.
