I am thinking of joining the original cage we got for Berta to the bin cage.
I am worried that the tubes might be too small as I think they are designed for dwarf hamsters. Can you tell by looking at this pic if they are too small?
I could measure them but don't have a tape measure to hand. Berta can fit through them at the mo, but am wondering if it is worth it if she will grow too big to go through them soon.
Alternatively, I also have another bin cage that I could add but thought the cage might be a bit more interesting as it has another level. I was not planning on leaving all the tubes in because Berta just liked to hide, bed and wee in them lol! I just wanted one or two to connect between the cages.
What do you think?
