The trouble with most solo cat toys is that they stop moving the moment your cat stops. A weighted tumbler does not. Knock it over and it rights itself, which reads to a cat as prey that got away and came back, and that single mechanism is what keeps a bored cat batting away long after a stationary toy mouse has been abandoned somewhere under the sofa.

The base is weighted so the toy rocks and returns upright rather than rolling off under the furniture, and the teaser heads fit into the top so you can swap them over. It ships with a feather head and a plush tail head, which matters more than it sounds, because cats habituate quickly and changing the thing that flicks about up top buys you a second wave of interest from the same toy. It measures 10cm across, in blue or yellow.

• Self-righting weighted tumbler base
• Interchangeable feather and plush tail teaser heads
• 10cm diameter
• Two colours, blue and yellow
• Built for solo play, with nobody holding the other end

On feathers. Feather and plush heads are consumable. A determined cat will strip one eventually, and shed feathers are worth picking up rather than leaving about to be swallowed. Check now and then that the head is still firmly attached, and retire the toy once it starts coming apart. Rotating it in and out of a toy box also does far more for boredom than leaving it on the floor permanently.

Who it's for: Indoor cats and kittens who need something to do on their own, and owners who would rather buy one toy with two heads than two separate toys.
