I don't know Queen's siblings of course cause she's a fish lol.

I don't know my cat Bobo's siblings.

And technically I don't know Kishii's siblings, but I see them alot. After I bought her cause she was the last lonely rabbit at the petstore(and people didn't want to buy her because she was not a tiny baby bunny, she was a bigger grown up bunny) I went back to the petstore to buy supplies and I realized that whoever Kishii's mom is, is used for breeding those rabbits all the time. I see new black bunnies in there once a month and they all look the exact same as Kishii and sometimes have the same blue eyes as Kishii.

I feel bad for the poor mother rabbit who is being breed all the time for a petstore
