I recently added two new kittens to my family and I have a litter question. We have four litter boxes for them and one is a Littermaid. Since the Littermaid requires a good clumping litter, someone recommended Scoop Away (which works well). I bought two tubs of Scoop away and didn't realize there were different formulas. I ended up with one Multi-cat (scented) and one Unscented. After doing more research I learned that cats don't normally like scented litter, but no one told my kittens that that - they use both. I would like to use the same kind in all the boxes, but I'm not sure if I should stick with the Multi-cat formula (which I like) or the Unscented (the one my kittens are "supposed to prefer").
