So I bought two of these. One for me and the house cat and one for my niece and her garage/indoor cat. My cat is nearing her 16th year in the world and loves attacking these balls…when she is in the mood and not sleepy. They are great to throw at her, as she will bat at them or catch and bite them. They are super light weight and will not hurt the cat even when triggered by the gun. The gun will launch the ball a good yard or so, but it’s much more interesting if you angle it up and towards the cat as they will watch and attack as it falls. I have tried endlessly to make a video but she stops every time I hit record. It’s not just with this toy but with anything I try and catch her doing…hit record and she is suddenly on her best behavior or walks away. :/ I recommend this product for bored household cats and I think even the young ones would have more fun with it. I should mention that the gun noise might be a bit jarring to cats, but if you put a small hair tie (like the small clear ties) around the back pull- piece (this is the piece you pull back to cock the gun and put a soft ball in the chamber) it mutes the sound of the gun being fired. Overall, the cat and I are happy with this product.
