Our vet is big on natural wood perches. W and the tiels have plenty of T4W and TNT perches.
I don't think this perch (above) would be bad on W's feet. It's been in his house before, but I don't know for how long. He must have sat on it. You can see it is not brand new. I don't remember.
I removed it after the vet said only natural perches - but wouldn't those kind of sandy perches help trim his talons? (Are they called sandy perches? I think so, but...)
Anyway, this seems to be an OK perch, yes? It's not like W does not have a bunch of others to sit on.
