DO NOT STEAL

Spoof or Not: No
Cat name: Yarrowstripe

I rarely see a cat with the prefix Yarrow, I feel like the prefix Yarrow should be given mainly to cats with high potential. Usually I wouldn't like the prefix stripe for a cat with a prefix like Yarrow but I think the suffix really fits. You get 9/10

Appearance: Yarrowstripe is a long bodied grayish silver tabby she-cat with white unders and chin, with lime green eyes. She stands tall and has a very fluffy tail. However, she does have a slightly strange walk due to her having her daughters during her apprentice moons.

I like the appearance and how she has a fluffier tail but the length of the rest of her fur is shorter. I'm not entirely sure how giving birth at a young age has to do with the way she walks though. (If you inform me and it makes sense I'll raise your score) you get a 9/10. You answered my Question

Personality: Prim and proper, Yarrow is always seen as motherly and willing to help the clan. She doesn't have a short temper, but is known for holding a grudge longer then anyone in the clan. She loves her kits and former mate, but doesn't hesitate to correct them or beat their tail with a swift cuff to the ear or wack of the paw.
Special Traits: None
Likes: Her clan, cleaning around the camp, flowers, her kits, looking at the stars, StarClan.
Dislikes: Fighting, blood, spiders, voles, dirt, her name.

I like it when cats have no special abilities, it's good to have a semi regular cat. (I say semi regular because there really is no 'regular' for and Oc) I read ahead for the explanation about her name and its sad and I love her much more now. Is there a reason she doesn't like voles or is it a kind of thing like some people don't like things but don't really know why? You get 9/10

Clan: GrassClan (Founded somewhere in Canada, it's first leader being Grass-star. Known for their impressive comeback from a recent murderer murdering half of their clan)

I like that you added the clan history and also just wanna day he should have been named Assstar if you know what I mean. I also have a clan named Grassclan (I co-own it with Cat_lover321 ) you get 8/10

Position: StarClan warrior now, use to be a queen

Age: 45 moons at death

(Ex) Mate: Tinyshadow - a small, miniature dwarf brown tabby with wide light green eyes with a white underbelly and paws. Alive.
Kits: Redberry - a lazy russet and white tabby she-cat with blue eyes, one she has a hard time seeing out off. Alive.
Clearpetal - a fiery tempered gray she-cat with a light brown underbelly. Has clear green eyes. Alive.
Deerkit - small dusky brown tabby that still had his baby blue eyes. Dead.
Other Family: Mother - Russetfeather - a reddish colored tabby with a white underbelly and tailtip. Has clear blue eyes. Dead.
Father - Rainswirl - grayish silver Bengal Tom with green eyes. Dead.
Half-Brother: Stormpaw - dark gray tom with paranoid blue eyes. Status Unknown.
Apprentice or Mentor: Ex-Mentor - Cindershade - tall dark gray tabby with dark golden eyes. Dead.

I like the family and mentor! They have good names and appearances. I checked and made sure Yarrowstripes appearance was genetically possible and I was happy to see that it is! 10/10

General Other: Was killed by the murderer. Part of my Mafia book.

I might have to check out your mafia just to read it. ;)

Backstory: Yarrowstripe was originally named Streamkit, and was born with her brother, Stormkit. From the time she opened her eyes, her mother trained her to be a proper young she, making her put others in front of herself, got onto her when needed, and over all had a strict kithood. Her brother wasn't left out however, though it was their father that discipline him the most. The nursery was pretty much filled to the brim with new kits, but Streamkit was very close friends with Oakkit and his brother Bigkit, though her and the first of the two got along a lot better. When they became apprentices, her and Oakpaw started to grow a lot closer, but to her and her family, things went down hill when one day Stormpaw went missing. Thought the two weren't all that close, it still struck Streampaw hard. Oakpaw seemed like her only support at the time, and chessired him deeply for his time. However, when she was still an apprentice (roughly 11 moons) she found out she was having kits. The medicine cat at the time was known for gossip, and after five weeks of her hiding the pregnancy, the words spread worse then wildfire. The leader at the time was furious, and demanded to know who the father was. Of course, since she grew up being told not to lie, she told the truth, saying the kits were Oakpaw's. Instead of casting the two out, the leader gave them a much worse punishment. He made them warriors early, but changed their names to both show their mistakes and to humiliate them. Yarrowstripe was renamed to that because of her mother's disgust in her, saying her actions reminded her of the horrible taste of yarrow, whilst -stripe was for how she wouldn't be able to hide her mistake like she couldn't hide her stripes.
Oakpaw was renamed to Tinyshadow, for his size (which he was very self-conscious about) and -shadow for how his mistake followed him like his own shadow. The two were also shunned by a lot of the clancats, though their old denmates stayed by their side. Cindershade continued to train her secretly, but made sure to not go overboard. When she had the kits, she hoped everything would go back to normal, but it didn't. Redkit and Clearkit were always begging to go out of the den, though Redkit was a lot lazier then her sister. Before her kits could meet their grandparents, both Russetfeather and Rainswirl were killed by food poisoning from rotting prey a few of the newer apprentices brought back without knowing. After Redkit and Clearkit were made into Redberry and Clearpetal, Yarrowstripe learned she was having her second litter. Only they weren't Tinyshadow's, but his brother's, Bigstep's. She tried to show she wasn't, and kept telling everyone that StarClan was just blessing them with a lot of prey, and she was just gaining a lot of weight. However, while she was on a hunting patrol, she was forced to hide and have them. Two of them died do to her neglect to tell the medicine cat, but one lived, who was named Deerkit in honor of Deer-runner, Tiny and Bigs's father. The ones on patrol with her were shocked, but luckily understood why she didn't want to have them at the camp. They promised not to tell, and made it look like they were Tinyshadow's. He bought it for and few weeks, until Yarrowstripe couldn't take lying to him anymore and told the truth to him.
He was hurt and angry at her, and held it against her for a while, but she accepted it. Moons later, was went the murders started, and the culprit killed Deerkit to 'cleanse this clan of all of it's mistakes'. Before she died, she was able to talk to Tinyshadow, and had a small heart to heart with him, the both realizing their mistakes. That night however, she was the next victim, being chased up a tree before being attacked and falling off the tree thanks to the cat. She was able to be reunited with her family and Deerkit, but learned her brother must have still been alive, seeing as he wasn't in StarClan. She looks over her living family now, showing small signs she's still looking over them.

Overall you got 65 out of 70 you would have gotten better but I had a few questions. If you answer them you may get a higher score.
