The bottom line
Catit's Senses 2.0 Collection includes a variety of interactive toys for feline mental stimulation. Each color-coordinated green-and-white toy can be purchased and used on its own but combined, they form a cat playground with endless combinations. Not every toy is worth the money — my cats, for example, showed no interest in the standing Scratcher — but the majority are unique, well-made toys that most cats will enjoy, particularly the interactive Food Tree, Digger, and Super Circuit.
Pros: Collection stimulates different forms of play and includes scratchers and food toys, made with BPA-free plastic, easy to clean, easy to rearrange to reignite cats' interest
Cons: My cats wouldn't touch the Scratcher and it's difficult to lock the vertical rod into its base; my cats preferred the Super Circuit when it was combined with other toys in the collection; difficult to remove the covers on the Super Circuit after locked in place
