I don't like holes in my screens so I use 12-30 pound test fishing line to make loops through the screen and tie in place. You then can twist vines to the loops.If you want to attach branches, drill a small hole on them and tie the line through it, works awesome every time and lasts forever...
Some pics of my previously described "Chameleon Phone Booth". Note Ziggy my Ambanja hanging out on the polypropylene rope I use for weatherproof "vines" and the screen door for the front.
I have used prehung aluminum screen doors, framing and supplies from lowes or Home Depot that they stock for building pool cages. After a learning curve, they work for anything 2 feet to 200 feet without reinventing the wheel. There are many sites on the net as well under DIY pool cages.
Love them all. I can't wait to see more species here. Hoping for damaranum and merus for myself one day. Truly fantastic. My pumilum and transvaals are growing like mad. I am starting to get suspicious my female transvaal may be more than just fat. Have you had pairs reproduce under 1 year old?
My bradys from Paul are also all doing great. I do have to say that when one buys a super rare exotic species, they are assuming a huge risk and that should be the fun. Past 5-7 days, the health of the animals should be on the keeper, not the breeder or importer. If the animals die past that...
