Not sure if I can even post this or where to post it, so mods please feel free to move where is should be.... I have a friend who got the cat genie and loves it, so I am looking for some more input on the product... Do you have one? if so what are the pros and cons? I have to older cats (6 next month) and to new kittens (9 weeks today) would it be to much for them, should I get 2 of them... thanks a bunch...
