I'll leave my tubs open if you leave your exo's open and we can see who likes what better :p haha

I kinda see what you are saying but you are wrong about passion. There is no spot cleaning on newsprint. Cleaning a 100 tubs on newsprint would take the same passion as spot cleaning 100 cages. I think it takes the same amount of passion no matter what you use.

Do people who keep birds have no passion for them?
