Cats love mostly the things that you do not pay for, except this one! I have an orange cat and she is very particular about her toys. Most cats are fine with paper on the floor, a sack, or even a shoe box! But these small tennis balls are perfect! She is able to pick them up in her mouth, flip them in the air, and roll/kick them to us. I find the irony in the fact that she is orange and I have other balls for her to play with, but she will choose this ball over any other! Including the ones with the bells in them! It is so adorable! If you are a cat lover, these balls make a great treat! The next improvement I would make would be to make some with cat nip inside, but with the same tennis ball material! Thanks!
My cat is also very picky about what he plays with. We've wasted a lot of money on this and that, but these little balls have been in service for over a year and are still going strong. They're nice and solid but light enough for him to pick up with his mouth or his claws. He really enjoys holding on to them with his front claws and scratching the heck out of them with his back claws. The fuzz does start flying with that kind of treatment, but so far it's been easy enough to take a pair of scissors and cut away the fluff sticking out and return the ball to him for further beatings. They're also great for tossing and rolling, even inside, and he'll chase them all over the place. I'd definitely buy another pack or two of these, especially since I know they'll last quite a while.
