I have had Heather's swings for more than 6 months now..They like the ledges and will chew the edges of them but not enough that they can no longer utilize the ledges. They REALLY LOVE
the mahagony ledges that I bought from Heather's website..They are $7.00 for a large ledge and it is about 2 inches thick and relatively the size of a large cup saucer or dessert plate. They have chewed the edges but have not even touched how big this thing is..They love to hop from ledge to ledge...I will post pics of my cages for both the boys and the girls as soon as I fugure out how to also!
All of her stuff is relatively big and you really cannot tell from the pictures...Her toys are great...they LOVE the loofah slice toys also.
Good Luck on your hunting for things to do...I also have her swings...once you see pics you will get an idea of how big her things are as compared to the Chins using them!
