I made this gym/perch because their old one is looking pretty chewed.
It's surprisingly stable but the leather knots do loosen over time. I replaced the old 'perch' part on their old gym with a new piece of Grapevine - so this one isn't being used right now.
Laker & Rio both like it - maybe I'll alternate the gyms until i decide. I was also thinking of dismantling it & trying for another configuration altogether....
