Yes I have some nice little roost boards that could slip thru the crate wiring. I also like to drill a hole thru them or a good branch and then can wire them to almost anything at any angle even if they won't slip thru the crate wires.If it is one of those wire dog crates, you can slip a board through the wiring of it to give them a place to roost like I did for my grow-out's.
