No, I'm not going to make this too long, but I do want to say that I have unfortunately come across some flat out horrible names in my time. 

What to Avoid Naming a Kit For:

Eye Color

Debilitating Defects

Genetic quirks that will impact the kit's life

What I Encourage:

Pelt Color (Ex. Gray, Pale, Dapple...)

Event at Birth (as long as it ties in to the kit's appearance)

Naming the kit for a dead relative (same as above)

Elements (Waterkit, Flamekit)

Plants (Leafkit, Oakkit)

Animals (Shrewkit, Featherkit)

Phenomena (Stormkit, Sunkit)

What isn't even Allowed:

Star- (leader's suffix only!)

Moon- (It is suitable for a suffix, though)

Spirit- (Should be avoided at all costs)

That's it for prefixes. Now on to suffixes!

There are multiple categories of suffixes. They are Appearance, Correlation, Personality, and Skill.
