I... don't actually know where to find a female cat that would be okay with suddenly being a mom. I mean... what if she doesn't want them? That would be terrible. Someone already left them, and then it turns out their new mom doesn't want them either.

[Souji doesn't remember, but Hijikata probably recalls a little boy who was given away to a dojo for his own protection, and then didn't feel wanted there either. Which might be why Souji looks so upset at the thought.]

I'm sure we can find out what they need to survive. And then when they grow up, they can probably take care of themselves. [Except probably not because Souji will spoil them, but shhh.]
