I've had a cockatiel in a Prevue Hendryx 16.75 x 17.25 cage from 1995 - 2020 when he passed. 25 years ago knowledge wasn't so much there. Getting a new baby. Different posts show different size suggestions. There are a lot of wonderful cages out there and cages above 22 x 17 give or take are height about 58" which is higher than me so not option. Been told by breeder and cockatiel owner that that is fine size wise. Folks - what size cage do you use?
