I got these free from redeeming points thru a cat litter company, I wasn't expecting much from having cats my entire fifty years. First star is just for attaching the toys to the cardboard with cotton string (instead of plastic)!
I tossed the banana towards a now-indoor feral cat that is still skittish around people and he started playing with it immediately. Next I tossed the orange toy to a resident cat that we've had for four years, he immediately started playing with it. I figured they had to have catnip inside of them - nope, they just love the natural wool.
I have purchased so many cat toys over the years, and even made my own; it's very rare that cats take such an immediate liking to a brand new toy. I will definitely be purchasing more, and recommending these!
