I have a cage that I don’t put the grate in since one of my parakeets had deformed feetsies and the vet said it could make her be in more pain, and want to keep it grate free for my new bird, are there any suggestion for a lining material for the tray? I can’t do paper because my very first bird died for an impacted crop because of the paper. Any suggestions should be much appreciated! Current plan is just unlined and to clean the tray fully, but I feel that that will get exhausting. Any suggestions will be much appreciated!
