Question

Is this a good definition

A cat is an animal with whiskers.

Answer 1

Yes, but it could be more thorough, like for example:a small domesticated carnivorous mammal with soft fur, a short snout, and retractile claws. It is widely kept as a pet or for catching mice, and many breeds have been developed.

Answer 2

This definition is not enough to describe a cat.

Explanation:

No, this is not enough definition to describe cats. Also whiskers are not exclusive to cats only. There are many other animals with whiskers.

This sentence is just a part for the introduction of a cat.

Rather we can say many things as - a cat is a carnivorous animal and also kept as a pet. It has whiskers and feast on mice etc.
