My kittens have all kinds of toys, some of which I spent much more money on, but these are by far their favourite. I have hardwood/tile floors through the house, so the springs roll/bounce/skitter satisfyingly. They are a perfect size and shape for the kittens to pick them up in their mouths or their claws to throw them around, so they can play by themselves easily. They do get lost in small spaces easily - every day I am retrieving them from under the fridge, the TV cabinet, the computer desk... I thought they would need frequent checks for chew damage, but I'm finding they stand up to kitten chewing much better than I would have expected. In conclusion, I am ordering a second packet of these!
These are such a simple idea, but my kitten absolutely loves them. She hasn't stopped playing with them since we got them, its the one toy I can leave out all the time and don't need to rotate to keep her interested. Safe enough that I feel confident leaving them out for her to play with when i'm at work too. Brilliant cat toy!
