One of the things I bought was a swing similar to this one: JW Pet InSight Sand Bird Perch Swing. After reading and research, I realize that sandpaper perches are not a good thing.

My conundrum is they seem to really love this swing. It's wide enough for two of them to share it and swings freely. They use it all the time and sometimes even roost on it at night. How important do you think it is to replace this ASAP? How likely is it that this one swing will cause foot problems? (The rest of their perches are all natural branch perches.)
ETA: I'm thinking of trying to smooth it out or wrap it somehow so it's safe for them. Any ideas?
