I've been looking for an upgrade for my two boys and found this bird cage listed. Its dimensions are 26x18x37 (I'm assuming inches, but it doesn't say) which according to online cage calculators should be fine for two rats. The flat part at the top also opens up. Would I need to add levels, or would it be okay filling the space with baskets and hammocks and such? Any immediate red flags?
