Sandy Perch perches have come up on a couple of threads recently and I wanted to know how many people use them or other products like them. Everything I've read has consistently warned that these can scrape up a bird's feet and either suggested not using them at all or using them in conjunction with other perching surfaces and being very careful to look for any signs of sore or abraded feet. I did get one sanded perch by Sweet Feet that has a strip along the top where there is no sandy material, but I've been avoiding the fully sanded ones for the most part. My portable stand has a Polly's Sandwalk perch built in and Scooter doesn't seem to like the surface much anyway.
I can see why they'd be the #1 choice for a shower perch since they are nonslip.
So, do you use these? Ever had a bird get sore or injured feet?
