Only for really small treats
My cat was immediately interested, but unfortunately it's a bit hit and miss and will only work with really small treats. The Dreamy treats my cats like is too big for it, and it means they get stuck in the opening and only fall out sometimes, making the cat lose interest quickly. It is easy to attach to either thicker or tinner surfaces. The lid is not secure but the toy overall is sturdy and well made. If your cat likes small treats, this might be a good choice.
