Ravens bio once again

I'm doing my bio again since mine was deleted. (Sighs). Here it is.

Personal Information
Name: Ravensky
Age: 13 moons
Gender: She-cat
Personality: Is usually a kind, cheerful, forgiving, and humorous cat. Can sometimes tend to be dark or gorey. Has lots of energy, bravery, intelligence, boldness, and determination. Is a natural leader being protective, loyal, and is a quick thinker. She may not have the best patience with kits, but tries her hardest to help anyone. Her past made her have serious trust issues and depression. She has some charm and tone which makes her a lovable cat.
Likes: She likes the feeling of freedom. She tends to pull tricks on cats which she enjoys. One of her favorite things are to run and climb trees. Anything to get the wind in her fur!
Dislikes: Any day that is above 60 degrees.
Fears: Being beaten in battle. She also has had anxiety attacks before being in ThunderClan and fears she may have one again.
___________________
Clan and Status
Clan: ThunderClan
Rank: Warrior
Family: Deceased
Mate: N/A
Kits: N/A
Mentor: N/A
___________________
Appearance
Fur: Her fur sheds season to season. In the summer and spring it is a brown, fall a black, and winter a white. She infers this happened when she was kept in a twoleg white den.
Eyes: Green but yellow in the right light.
Appearance: Is an abnormally big Maine Coon with a fluffy tail, ear tufts, long whiskers, and huge paws, giving her a cute apperence from behind. In front, her green/yellow optics pop out of her round face which has a scar running from across her eye to her tail tip. Fur has grown over it but occasionally shows up, usually when she sheds. Her muscular, long legs fit her huge frame.
___________________
Skills
Strengths: Her strength is strength. Her huge build makes her one of ThunderClans best fighters.
Weaknesses: Is not the best runner, and does not have a lot of stamina.
Combat Style: She usually runs up to her enimies and throws them off with her weight and pins them. If they are too heavy for her she will hide in bushes or tall grass and wait until they are close enough for her to pull their tail. Then she will attack with full force.
___________________
History:
Was an orphan as a kit after being abandoned and had her siblings die infront of her.  Had been a rouge for as long as she can remember, making enimies and allies. She was in a fox battle which gave her the scar that swallows her entire body. Was captured and brought to a giant twoleg white den where her and a bunch of other animals were tested on. Was released into the wild after one moon and started her anxiety attacks. She needed to find help so she traveled to the Clans, where she was adopted in ThunderClan.

It's a nice bio- I know what a pain it is to rewrite entire character pages!

Unfortunately, I don't understand how it's possible for a cat to go from brown, to black, to white? Cat's don't possess the ability to change fur color like that? I want to know your thoughts and reasoning about it. o:

I'm so much of a looser that I was surfing the web and found cats like shed and change eye and fur color due to genes. I was also sick of not finding good profile pictures. I know it may sound wierd, but it's true. She's also getting old.
