I'm probably too old to be writing this stuff, but I don't care! Also I haven't touched a Warriors book in years, so I went ahead and just made my own clans so that I wouldn't mess anything up :P
The medicine cat's first reaction when she saw the obviously deformed kitten was to throw it in the nearest body of water. No one needed to know it ever existed. She pulled the kitten away from its mother and gave it to her apprentice with the solemn instructions, hushed, so that the mother wouldn't hear.
Soon after the wicked deed had been done, two Bogclan cats found the thing floating among the currents. "A kit?"
"A kit!"
They jumped into the water and one grabbed the lump by its scruff. Once they pulled it out, they noticed that where most kittens had two creases where their eyes would be, this kitten had one huge crease spanning much of its face.
"We ought to take this to the medicine cat, shouldn't we?"
"Should we? This kit seems like a bit of a lost cause. I bet it'll just be blind."
"Well a kit is a kit, and I don't want to stoop to the level of the clan that left it here."
"If the kit has another clan's blood, then who cares what happens to it?"
"Me!"
And so the two cats left their patrol early to gift the kit to the Bogclan medicine cat. This medicine cat decided to give the kitten a chance, and lent a nursing mother to it. The mother was skeptical, but it was still summer and the clan had freshkill to spare.
The cat who had originally found it hung around the nursery for a little while, endeared by the little thing.
"Do you want to name it?" asked the medicine cat.
He jumped. "Gravelfur, you scared me! But me? Why not the mother who is nursing it?"
Gravelfur shrugged. "You seem to like the kit."
The cat thought for a moment trying to think of a good name. "I'm tempted to call it 'Eyekit' because that's a really obvious thing to think about when you see it, but I don't want to make its whole life based on its deformity. How about 'Swampkit' because that's where we found it?"
Gravelfur nodded. "That sounds appropriate." He looked into the nursery to see the mother licking Swampkit. "She's warming up to it, that's good."
Swampkit tended to stay in the nest with its nursery mother while the other kits played. They were all a few moons older than her and so she avoided them. Her eyes hadn't opened, and she had been told that they probably never would. She would be blind, apparently.
Eventually curiosity overcame the kit, and she began to walk. In no particular direction, because she couldn't see, but nonetheless she walked. First she walked into a nursery mother, who gently pushed her into a different direction. Swampkit walked in that direction where she came in contact with- another cat? She sniffed, and realized that this was another nursery cat. Which one was her mother? She couldn't remember.
Off she walked in another direction. This time hitting a wall. It didn't hurt because her walk was very slow, and her gentle fur and jelly-like body protected her.
"Oh Swampkit, so innocent."
Who was this? She did not recognize the voice. "Who?" She mewled.
"Talking already? Quite the learner. I'm Grasswhisker, nice to meet you! I named you, ya know. Aw you're so cute."
Swampkit felt a warm comforting tongue brush across her fur as Grasswhisker gave her a quick lick. "You named?" she questioned.
"Yep! I'm practically your father, if Mudmellow is your mother."
"Father?"
"Ehh, like the tomcat version of your mother?"
"Mother?"
"You see that cat who was nursing you? Wait that's a fishbrained question, of course you don't."
Grasswhisker grabbed Swampkit by the collar and lay her down on the nursery mother. "This is Mudmellow, she's your mother, one of the Queens of the nursery."
"Mudmellow!" exclaimed Swampkit excitedly. She got licked again.
