Thank you dreamtree
I do love having them in the one room. Though Boris's ranch sits on the landing outside the room and Sparky and Snappy's playben is permanently set up in another room (I'm a little bit lazy as I like to get them out most days so I tend to just leave it up
) Pasha and Artie both have play boxes which are stacked so it's easy to stick the lid on and stack them up, Snappy and Sparky will probably get a box too once they seem confident enough for it
