I have, at the moment this picture was taken, clean living quarters for my girls. And I fenced in a run so they can run out and play and back in as they choose, under my watchful eye of course. And the small pen is for my guinea pigs, Rocky and Ollie

 

I have the same tunnel you have in the first pic! It makes crinkly noises when they go through it, right?
Mimzy likes it but I can't use it really because my bird gets scared of it & starts doing a warning scream :/
