Got this for my old lab mix to keep her off the hard floor when I am not home. I took out the tray and put a large memory foam dog bed in it and use a water proof pad on top just in case!  I felt guilty at first but she actually likes it and goes in it on her own, no more guilt!  I should have done this sooner as she gets around better not sleeping on the hard floor and has plenty of room with this xxl crate. Be sure to get a water dish that mounts on the cage so your pet will have plenty of water when you are away.  We love this crate and so does our  old girl. Wayfair had the best price I could find for a 54" crate. The metal tray was noisy and appeared to have possible sharp edges on it but since I am not using it I give the crate five stars.
