What is up with the cat in IQ ball?

It sounds like you're referring to the "IQ Ball" toy, which is a transparent plastic sphere filled with a liquid and a small cat figurine.

The cat in the IQ Ball is not a real cat. It's a plastic figurine that is designed to move and spin within the liquid when the ball is rolled or shaken. This creates a mesmerizing and entertaining visual effect.

The "IQ" in IQ Ball is a bit of a misnomer. The toy is not actually intended to be a measure of intelligence. It's simply a fun and visually stimulating toy.

Here are some possible reasons why the cat is included in the toy:

* Appeal to cat lovers: Cats are popular pets and many people find them adorable. Including a cat figurine in the toy is a way to make it more appealing to a wider audience.

* Visual interest: The cat's movement within the liquid creates a visually interesting and captivating effect, making the toy more engaging to play with.

* Simple and fun: The IQ Ball is a simple toy with no complex rules or instructions. The cat figurine adds a playful element to the toy, making it more enjoyable for children and adults alike.

Ultimately, the cat in the IQ Ball is there to add visual appeal and entertainment value to the toy. It's not meant to be a realistic representation of a cat or to promote any specific cognitive skills.
