I wanted to let you know the experience we had the day before yesterday with our Ferplast Piano 6 cage. We bought it only a few months ago, and though it's a good size, to me it's proved unsatisfactory in terms of strength and safety. Maybe I got a defective one, but the day before yesterday a *very small* paperback book slid off the shelf above the cage (the shelf is only about 8 cm above the cage, it didn't have far to fall, and the book was very light.)
It landed on the middle of the cage roof, and the roof panel collapsed into the cage.
Thankfully, both my budgies were all right. Scared, but all right. They got out of the way of the falling panel before it hit them, but I was appalled. At first, I thought it was my fault - that somehow I'd put it together wrong, but closer inspection showed that the plastic clips holding the roof panel in place had sheared off, causing the collapse.
We have now purchased a more solid cage (The Liberta Flight Cage), but I wanted to warn everyone of what we experienced. We were really lucky our birds weren't hurt or worse, killed by what happened.
As I also have this cage, I wanted to investigate my own cages safety after this concern has bought up.
Kyrion, you said the roof panel collapsed and I take it you mean just the barred section in the middle of the cage?
If anyone has or is intending to buy this cage, that section comes already put together. I gave this section in my cage a very hard pull and it's very sturdy, so I believe for Kyrion's to come away with only a light book falling on it, you must have a faulty cage.
I personally, would complain to Ferplast, going through the company you purchased from and if you can, add a customer review with any photographic evidence you have to back up your claim.
I'd also suggest if anyone has this cage and is concerned by the safety, they should use cable ties like Deb has suggested helping secure the cage top. If anything fell on top, I do not believe it would fall through in the same way.
