This is a set including a cat litter box developed by a veterinarian for lions, and two 5L bags of odor-absorbing litter. I received this when I adopted a rescue cat, but I'm selling it because I already use a system toilet. It's new and unopened. Please understand that this item has been stored at home before purchasing. It will be shipped with the shipping label attached to the original box. I'd like to sell this to those who have just adopted a cat or those who need it for multiple cats. Thank you very much.
