Half or full blooded siblings work for me depending how how the other cat looks.
The cat in question is a long standing OC I've had that has honestly never made an appearance, just been an important part of the lore and backstories of various cats. Butterball is a farm cat, and a high quality one as well.
His mama was a purebred, but none of Butter's offspring have to even remotely look like some sort of purebred, it just happens to be part of her own story.
Anyway, his mother joined the Clan's and, being close to her, has been searching for her, and traced her to the general area of the Clan's. The problem is, it's been so much time, and the Clan's are very large and territorial, making it difficult to truly search the Clan's.
Along the way he has met, befriended, and formed romantic interests in a variety of the Clan cats he's spoken to.
I have no problem actually role playing him if we decide that's what we want.
If Wisteria grew up on the farm with him, you and mom cat can figure out how that works lol
That being said, Wisteria would have a few half siblings, a variety of aunts and uncles, and a grandma if you are open to this idea.
