How to Name Your Cat

Before we dive into the best space names for cats, it’s important to understand what goes into selecting a good name. You can’t just randomly pick a space name and expect it to fit perfectly with your cat’s appearance and personality.

With that in mind, you want to get to know your cat before you name it. Look at their coat, fur, and size to see if any names fit their appearance. From there, consider the cat’s personality. Your cat’s personality will help to narrow down your selection significantly. Once you have a list of names that fit your cat’s appearance and personality, you can make the final decision by picking out your favorite name.
