Author's Note
Some things for the warrior cat ones (like age) won't be confirmed so like certain things like age and stuff won't be in here lol, also tom means male cat and she-cat means female also there's two backstories but one is a basic summary of her past and her life and the second one is her POV  like a short story type thing, also I put a lot of terminology for those who are unfamiliar to the series, also for those who do know the books this is an au where Jayfeather is now the only medicine cat and Firestar is still leader, also Jayfeather's mentor was Yellowfang because it's an au lol

Name: Snowbird

Eye Color: Left eye is blue, right eye is green [heterochromia]

Kits (first litter): Petalfoot [she-cat], Minnowclaw [tom], Applenose [she-cat]

Kits (second litter): Sparrowfoot [tom], Wolfclaw [tom], Birdsong [she-cat]

Backstory: at one point she was a kittypet [pet cat] but then her favorite twoleg [owner] died and the other one left without her to she became a loner [cat who isn't in a clan but is neutral towards the clan cats] and one day she fell in love and had kits, but her mate [basically her cat husband] died before her second litter is even born, and she's living in a modified abandoned rabbit burrow on distant Thunderclan territory, not at the very border mark but like in the middle of the territory but not actually the middle of the territory as she's closer to the Riverclan border than Thunderclan camp, eventually she gets discovered with her three eldest kits and eventually agrees to join Thunderclan, where her youngest litter of kits are born and raised and they all grow up there happily, also before joining Thunderclan her name was Snowy

Backstory 2: I didn't find food again and we're all hungry, while my kits are four moons old and I could probably teach them to hunt as well, I won't risk them ever getting caught by the group of cats that live here, they're too small, it's too much of a risk, even I'm at risk, but I can't leave because I don't have anywhere else to go, this is the only real shelter I can find, I entered the burrow and curled up with my kits, Apple, Petal, and Minnow, and I feel concerned that one of them may wander or end up in danger, I curl up around them and when I go to sleep there's a cat in the burrow! He has food in his jaws, I can smell it, we also can't see inside the burrows because it's pitch dark so we go by hearing and smell for the most part, I arch my back and my fur bristles with defensiveness as I keep the kits behind me, but they did bring food so I'm doubtful of if they're trying to be a threat or not so I decided to speak up "What are you doing here?!" I hiss defensively as the kits behind me are nervously curious about the strange cat as they've never seen a cat besides me and their father, but the strange cat speaks "I've come with a peace offering on behalf of our clan leader, Firestar, in case you didn't know this is clan territory and he requested me to lead all of you to our camp so that Firestar can decide what to do with you, I'll leave you guys to eat in peace, but I will be waiting outside so don't take to long" the strange cat spoke, dropped a squirrel down on the floor of the burrow and then walked outside the burrow and just like he said I can still smell him outside the burrow, I take a bite of the squirrel and leave the rest to my kits as I exit the burrow, I sit just outside the burrow entrance and I see the cat that was waiting for all of us, he's a bluish tabby cat, and his eyes look cloudy, he's probably blind, she looks at him with pity but as if he knows what she's feeling he glared at her, not in a threatening way, just in a way that showed annoyance, but eventually the kits climbed out of the burrow
