i do like the idea of texturing the perch!
i would NOT use that dye. if you have to wear gloves, its going to be bad for you and the bird.
i have thought of making a small PVC gym, but i wouldn't know how to design it! i do recommend getting vet wrap for it. i put some on my trees just to make a softer landing for them
I'm not sure which country/ state you're in, but i get my vet wrap from Dover Saddlery. it is $1.99 for a roll. make sure you get the 3M brand and not the "Co-Flex" brand. 3M isn't stinky or overly sticky, "Co-Flex" smells and stays sticky no matter how much dust and dander get on it.
im not sure if you have seen my trees/gyms around the forums. theses are kind of recent pics. only difference is in the fist pic, i have attached a *shutter* store bought gym on my window and in the second pic, i have all of the foraging toys in a wooden tray.
i made everything myself. i pressure washed my trees (water) but other people like to use vinegar. i like pressure washing because it takes all of the hidden dirt off and the tree turns a few shades lighter. if you search for "inspirational tree thread" you can see the before/during/after pics of my trees.
the fish tank on the left is gone and there is usually a bowl of seed on the cage
this is the store bought gym that i put on the window. Pickle trashes it daily with shredded egg carton and whatnot
for my other pets: cat, rabbit, 6 fish tanks, 2 fire belly newts, 2 african dwarf frogs, 22+ crayfish, fish
