Is a cage calculator good? I mean, I read on several sites that a cage must be 80x50x60 (in centimetres) (WxDxH) My cage is a bit smaller, but higher, so I searched a cage calculator and it said: 2 rats, if space is used wisely. How do you use space wisely? Hope you can help me out

When it says use space wisely it means making extra room by adding shelves, hammocks etc so the empty space height-wise is still usable to the rats.

There are already some shelves, so I think that's okay

Here's a cage calculator that takes shelves into account:
