Bio parents: Crowsage and Tarantulastar
Adoptive parents: Hummingbirdstar and Tarantulastar
Because Humming is so small and Tarantula is so huge, they didn't want to have bio kits together because of the health risks to her or the kits. (The fact that someone else, Ferndoe, had a difficult birth and had a kit with health defects because her mate was larger only solidified their idea [and their size difference is much greater]).
So instead they went the surrogate route.
It just so happened that Crowsage, a she-cat, had her own mate who she wanted kits with, but both being gals they couldn't do it on their own. They came to an arrangement that they would help each other have kits, and Crowsage would feed them until they could be weaned. If the litter was even, they would split them in half (Tarantula takes two, Crowsage takes two), if it was odd, Crowsage would take the majority.
It wasn't like splitting a family up. Sure, they lived in different areas, but it wasn't like living in different Clans. They wouldn't grow to be enemies or would have to fight against each other, and they could visit each other as much as they wanted, no big deal.
The families also made sure that the kits kept in touch whenever they could, but also kept apart long enough so that the kit Tarantula and Humming got saw only them as his parents, and that Crowsage's kits only saw her and her mate as their parents (if they're together too much it gets confusing, especially with Crowsage having nursed).
ALSO! There will be a Clan-born kit that will arrive and be adopted by the family when they're very close to Char's age.
Char's pelt comes from Crowsage's main colour, which looks like a burnt version of either Smalljump or Tarantula, hence the 'Char'. It also leads back to the family friend and @elementaldeityoffood 's character, Sparktail.
@starfalcon555 finally got the design done after a while of struggling with it! (Trick is, change the base).
