Try covering it more . If it helps, why not. I think the reason we go for wire crates rather than the hard sided ones is fear of over heating. Unless you keep your home over 70 - 72 degrees or so that shouldn't be a problem. If you become concerned about that you can slowly move the cover back or use a sheet instead of a blanket. Zelda always preferred to sleep in a den. Either a hard sided crate or under something.
