# Cats - NFTs

## Cat NFT Types

Catopia's core NFT digital assets are cats, which come in four types. The rarity increases in the following order: A-I model cat, A-II model cat, A-III model cat, and A-X model cat. The higher the quality, the more visually diverse the cats are and the higher their COA acquisition rate.

## NFT Product Strategy

The official only sells limited quantities of the lowest grade A-I model cats.

A-II model cats, A-III model cats, and A-X model cats are evolved or bred by players using A-I model cats.

Players have sufficient motivation to improve the level and grade of cats.
