A soft plastic fish with a waterproof motor inside. Drop it in a shallow bowl or the cat's water dish and a sensor switches it on, so the tail flicks and the body darts around on its own with a small LED glowing inside. It runs on a rechargeable cell you top up over USB, and it powers itself off once you lift it out of the water to save the charge. Built for indoor cats and dogs that get bored and need a moving target to chase, it taps the same hunting instinct a laser does without you holding anything. Fair warning: it is a water toy, so you have to dry it off after each session or the electronics inside can corrode over time.

Pros

  • Turns itself on in water and off when you lift it out, so the charge lasts
  • Moving target triggers the hunt instinct the way a laser does, but hands-free
  • Rechargeable over USB instead of eating through button batteries
  • Small and cheap enough to keep two or three in rotation

Cons

  • It is a water toy, so you have to dry it off after each play session or the motor can corrode.

Frequently asked questions

Does it turn on by itself?

Yes. A water sensor switches it on when it gets wet and shuts it off when you take it out, so it only runs while your cat is playing.

How do you charge it?

It recharges over a USB cable. A full charge lasts through several play sessions before you need to top it up again.

Is it safe if my cat bites it?

The body is soft non-toxic plastic meant for chewing and pawing, but the motor is electronic, so supervise heavy chewers and pull it if the shell cracks.

Does it work for dogs too?

Yes, smaller dogs that like water play chase it as well, though it is sized and paced for cats.
