My birds just love theses sandy perches, these perches helps keep their claws trimmed up some & they also like to play & chew them up, it keeps them busy, I've only had these about a month and my birds couldn't be happier

Keeps the perches cleaner, the nails shorter and the birds like picking at it.

I don't know if these helped trim or dull the birds' nails at all but it made cleaning the perches much easier

Only problem was the one thicker perch I have for variety

I know).I think you're supposed to just slip them onto skinny perches, but I have to partially unroll them, which can't be done without a little bit of damage and a loss of the roundness that lets them grip the perch

Fits perches perfect

Helps with keeping my parakeets breaks trimmed and the perch it’s on clean!

Love these sand perches
