or velcro. I prefer the removable cover as mine are diggers and it gets pretty dirty. I also remove the cover of the one in their crate, place the cushion inside in a large plastic garbage bag and replace the cover just in case there is an accident, so the cushion doesn't have to be washed. This has worked really well for us.
