Got my three this cage last night. What fun it was to watch them see the size of the play area. I put some java branches for them to jump to. I am using small chains across the top for hanging. Also hanging toys from the Java branches. I did modify the doors to open like a regular door rather then lifting them. They were very loud to lift. I got very lucky that A&E is only 22 miles from my house so I paid no shipping just picked it up. I have put two stealth wheels in that are side mount. Not sure i would put them to high as the wire is not as high Gage as some cages.
In the end I would give the cage and B+. As for the hours spent watching my three play in this thing that would be an A+++.
