This is a classic pair of cage bottoms!
+ The positives are that it has a removable bottom, so it can be cleaned better or even removed completely, allowing you to put a substrate in the bottom of the cage and avoid stuck bottoms.
- The negatives are that they have thinned the thickness of the metal and it seems more flexible, more sensitive.
- Also, in the negatives, we must emphasize that the older ones had a frame consisting of 4 horizontal iron/wires, while these have 3 and create a problem with some nests in their support. In a future update of the review, I will also include photos to better explain what I mean.
