Okay, I'm totally picturing this, it's great.
However I noticed yesterday evening that the male pea who sleeps on the floor now stretches just about from one side of the bird house to the other with his spiffy new train. All three of the males are looking quite dapper and elegant, with the longest trains they have ever had. Nobody's gonna fit in a milk crate, pillow case, or even a dog crate... and I have what I think is the largest wire dog crate made
(And their trains still aren't as long as Zaz's birds yet... but the oldest are only coming 4.)
I think I'm gonna have to go with the salting the dust bath with Sevin version...
