I would need a bigger room to fit the third DIY cage(the dwarf one)but being in a relatively small house anyways I could certainly manage to fit the guinea pig cage and DIY hamster cage and still have the bin cage and tank if I either moved furniture down a bit or got a smaller stand of some sort to put my lamp on.
That being said,I do have a ridiculous amount of books which I must find a place for first which is honestly the only difficult part but once that is done it won't be too hard.
Bambi's cage would be around 24" tall,which will be a very nice change for her so she can have a good sized wheel.She needs a new wheel though,she doesn't like things with holes for some reason and most things with holes get chewed at.With the Comfort Wheel having two very small holes in it as well as the spindle which she chews at very rarely,it isn't the greatest for her but I can always sterilize it and use it for another pet once she gets a better wheel.
Of course,I'd like to have a lot of nice things like a very fancy antique couch but I find the space taken up by future pet cages to be much more logical
I suppose in that way my pets will always come first,at least while I am limited in space.
