Realistically, probably the normal hamster. I think I'd be ok with that because I'd have functional hands. Like I know other animals like sheep can hold things but still..
I would be a cat, they're my favourite type on AC, you just can't beat Olivia, Rosie, Tangy, and Raymond ❤ they're so cute and I love when they sing around my island.
I'm thinking maybe a blue cat who is very "Normal" meaning that I'm shy and I don't really talk all that often. So I would be friends with most of the normal villagers.
