Names in the Warriors series are easy to come up with if you know which prefixes and suffixes to use.
A good Clan cat name follows these guidelines:
-has one prefix and one suffix
-doesn't include the most ridiculous names that are listed under "Names You Shouldn't Use" (optional because you don't have to follow all of my tips if you don't want to)
-easy to read in the story
-makes sense
A good Clan cat name would be any of the following:
(I know I'm using canon names; they are used as an EXAMPLE)
Colors: Redfur, Bluepelt, Whitepelt, Blacktail, Yellowclaw, Goldenstripe, Graypool
Plants: Lilynose, Mossheart, Rosebriar, Leafstorm, Vinetail, Daisyheart, Blossomleaf, Petalnose, Hollyleaf, Fernbelly
Rock: Stoneclaw, Pebbleheart
Water: Mistyleaf, Dewnose, Ripplejaw, Rainpelt, Poolcloud
Fire or heat: Sunstorm, Firetail, Emberclaw, Ashfoot
Air and weather: Breezewhisker, Blizzardwing, Rainbelly, Snowleap, Cloudheart
Trees: Birchheart, Cedarclaw, Beechpaw, Oakpelt, Willowclaw, Mapleshade

You can see these are excellent names for a Warriors fanfiction. But there are some you shouldn't use. These use prefixes and suffixes that don't sound right when used in a Warriors fanfiction.
