Correct pronouns: He/him or they/them

Twin reference sheet I did as a gift of one of my friend's ocs as an anthro, symbolically a mouse when not associated with scorpions and swans. He's lactose intolerant, so it's probably not a good idea to give them cheese. Despite being the younger twin, he was actually created by my friend before she created Jian. Makes his nickname of "lil skeleton" all the more applicable as the teeeeeechnically younger twin. (But really, who cares! It's like a 5 minute difference??!)

Jacob here is a quiet sort who loses themself in books often, frequently not having much energy to do things as they suffer from chronic pain due to fibromyalgia. Despite having a paper thin constitution in comparison to their twin Jian who gets up to much more than him, Jacob can be quite mischievous, and is very observant.

He loves cats along with his twin, and the ones I gave him all represent various feline inclined friends and lovers of his. ; )
