Hope you like, just a short one shot XD!
Frostpaw leaped on a squirrel and bit into its neck, killing it. She put it down in her assessment pile and then smelt her brother foxpaw and turned to see him creeping up on her, she hissed and leaped over him and hit the ground quickly as he hurled himself at her. She moved to the left quickly and racked her claws down his flank, pulling out lots of hair. He yowled and fell to the ground hissing. He hissed then leaped onto frostpaw, making her fall to the ground. Foxpaw batted her head then racked his claws over her nose. Frostpaw's bleeding nose scared her but she went ahead and chased her brother off with a bare of her large teeth. Her mentor bumblestripe walked out from behind a bush and purred "Very nice frostpaw that is how you protect your clan!" he meowed with a glint of passion for his apprintence. Foxpaw and glistenfeather, foxpaw's mentor, came out of the bushes and glistenfeather glared down at her apprentice. "My apprentice did well, too! He might not have won but his moves were also good!" she hissed at her littermate. "Calm down glistenfeather! I never said foxpaw didn't do well, he did very well at fighting, but what about what he caught?" foxpaw trotted through the bushes he came through and then brought back three voles, a blue jay, and two sparrows. So frostpaw brought her two squirrels, two black birds, and three rabbits too. "Wow! Frostpaw, where did you get theses rabbits?!" bumblestripe asked with a hungry expression on his face. "I found a whole nest of them! They were over by that bush with the red berries…" she licked her paws and as she did foxpaw hurled into her and pinned her down. "Did you touch those berries?" he asked his writhing sister. She nodded and got scared quickly. Bumblestripe looked at foxpaw with a questioning expression, "Those were death berries! W- We h-have to get h-her to c-camp!" he whispered. Bumblestripe grabbed her scruff and ran to camp with her writhing in contempt. He sat her down in the medicine cat's den and Greymist sniffed her fur. "Go get me some moss and yarrow!" she meowed quickly. Her apprentice, leafpaw ran as quick as she could into the herb store and brought back wet moss, and a leaf, carrying yarrow. Greymist chewed up the yarrow and pushed it into frostpaw's meowing mouth. The apprentice stopped mewling and lay, unmoving, in the nest. Foxpaw whimpered and the three warriors, Greymist, and foxpaw were all surprised to see frostpaw vomit out red looking berries and the yarrow mixed together. Frostpaw gasped for air and lay, shaking while vomiting. Greymist sighed "What a lucky apprentice she is!" she meowed.
And that is the story of how lucky cats can get when they have a wonderful medicine cat….
