Silvermoon

This name is super pretty! I like it! It also matches her appearance! 

Appearance- silver tabby she-cat with ice-blue eyes

Cliche. Silver tabbies are overused, and so are ice-blue eyes. Maybe change it to dark gray she-cat with silver patches and bright green-blue eyes? Green-blue eyes are very pretty. So are copper eyes, but that's okay!

She-cat

She-cats are overused. I like she-cats though! They are so cool!

MoonClan

Pretty name.

She snuck out of camp with two other kits - Brightkit and Crystalkit on her first day out of the nursery. Brightkit tried to hunt what looked like a mouse - not realizing it was a rat. This resulted in the death of Silvermoons father - who was a part of a nearby patrol who came to help. She , Brightpaw and Crystalpaw recived a prophecy from starclan after their first gathering . After her apprenticeship, Silvermoon fell in love with her former mentor, flameclaw, and they became mates. Soon a hurricane came to The clans, killing many of the cats and causing the leaders to decide to make a group leave the clans (willingly of course, they weren't forced) and find a new home. Flameclaw revealed to Silvermoon that he had only become mates with her to make a cat from OceanClan jealous and left with the departing group. Flameclaw's brother, nightshadow, comforted her, and Silvermoon realized that she had been so distracted by Flameclaw and the prophecy that she had missed what a great friend - or even mate - she had with her. She and Nightshadow became mates and had four kits, though one was captured by twolegs and now lives happily in the twoleg place.

Cats do not know what crystals are. Other than that, this is pretty origanal! It's cool! ;)

Personality- is mostly kind to all cats, though can become very annoyed and snappy with cats who get under her fur. Is very good with kits.

More flaws please. Other than that, it's cool. 

Mate - flameclaw, currently nightshadow

Flame- is one of my fav. prefixes, and -claw is kinda overused. Night- is cool. I love the suffix -shadow! It makes him sound so mysterious and dangerous! 

Kits-Mistcloud, Pebblestream, lunarstep, Darkpaw, later Coal

Cute names! But cats do not know what Lunar- is.

Rank- warrior 

Nice.

Overall, Silvermoon gets an 8/10 for some of those points I mentioned. Other than that, she seems pretty cool!
