RiverClan cats live on the reedy, pebbly plain near a river with a few trees. RiverClan cats are known for their skill at fishing and love for water. They also love beautiful things, and are known to collect rocks, shells, and feathers to decorate their dens. They eat mainly fish, but they can also eat water voles, shrews, and mice. They are contented, sleek, well-fed cats with well-groomed fur. They are known to be clever and graceful but are perceived outside their Clan as being stubborn and lazy (though they are quite intelligent). Sometimes other Clan cats call them "fish-faces", or "fish-breath".

WindClan cats are known for their love of open spaces. They live on open fields (also known as moorland) where they catch their main prey of hares and rabbits. Of all four Clans they are the least used to wet ground, preferring the grassy ground of the moors, which they sleep on. They do not like to sleep in the shelter of dens, because they prefer the fresh air. They often find themselves blessed to be the closest Clan to StarClan, both physically and spiritually, since the do not live in an environment surrounded by foliage that block their view of Silverpelt. They are generally the fastest and most quick witted.

ShadowClan's territory consists of pine forests and swamps. ShadowClan cats are skilled night hunters, relying on the cover of the darkness while hunting, as there is limited undergrowth on their territory. They also have the reputation as the most stealthy of all the Clan cats. ShadowClan's main prey includes frogs, snakes, lizards and other creatures that inhabit the marshlands. They are very proud of their 'fearsome' title and try to avoid asking for outside help. Kittypets have always been disliked by ShadowClan the most, and they quickly dislike any Clan that welcomes them.
