Gabby is her real name and fey is her middle name, she is a special case
she is the adopted sister to Gabriel blackrose but she didn't know that until her baby fur started to change when she became a tween and realized she looked more like her great great great grandma Daria and very great cousin Charli, when confronted by their daughter hover runs for the basement leaving damy to explain to their little tween about how hover found her on their doorstep sleeping as if dead, "but when we found you your baby fur was gray like your brother's".damy had told her and went on to explain that other then that they had no idea why she looked so much like their distant relatives.
Since her fur change she went through a few changes herself as the kids would nickname her the Frankin hog, she would get major mood swings and her body started to plump up and grow in all the many places.
here are a few short stories she experienced.

1:Shade was over at damy's house watching his niece Fei-Fei who had been getting into all kinds of trouble the last straw being her throwing a ball at his face, "you're in a time out missy", she huffs at him sticking her tongue out, "watch it, missy, I'm part cat ".

2:Hover walks into the bedroom and his wife looks at him with concern, "what's wrong? "she tilts her head until he lowers his head showing baby Fei-Fei chewing on his dreads

3:Damy walks out of the baby's room. eyes twitching, voice hoarse from singing nonstop, and hair a mess.
this combination makes her son Gabe laugh and this makes her angry, "I will go to jail today if a little doesn't leave for school in 10.9...3.2.", all that is left is a smokey smiley face where Gabe once sat,
"hey, love where did Gabe go so fast, WHOA", Hover stared at his wife, "my love you look...greeeeat".he grabbed his keys and ran.

4: fei-fei plays in the mud laughing as she throws big blobs of it at her brother as he runs past, "gabby". damy pokes her head outside, "get outta that mud and bathe missy". Fei-Fei huffs grumpily but yelps when Gabe sprays her with the hose, "let me help you sis ", he snickers until he notices her once gray fur now seemingly melt away, "uh oh", he ran
( 4 and 5 got switched by mistake)
5:Fei-fei is taken to her aunt remira's house who creates a temporary color to change fei-fei's fur back to gray, her uncle ash walks in and both make plans to play pranks on aunt remira (the slap was inspired by eric the creator of Sabrina online.

6:she's just being a moody newly turned teen who just got on her monthly

7:barely even sixteen Fei-Fei takes her grandpa shadow and great-grandpa sonic shopping with her when after moments of being in the changing room she realizes she forgot to bring the clothes in, so without thinking she throws open the door and right before she can ask them to hand the clothes over they both shout at her.
"GABBY", sonic shouts, "PUT SOMETHING ON"!. a random guy walks past letting out a whistle.
"GET OVER HERE YOU TRASHBAG", Shadow shouts chasing the poor guy outta the store.
"I need the clothes I picked out G.paw", sonic threw the clothes at her then pushing her in her slammed the door shut, "Don't do that to me girl" .he grabbed his chest sitting next to a slightly less angry shadow.
Fei-Fei shook her head slowly, "well cheaper than bodyguards".
