Really? Rabbit

NO. THAY ARE NOT.
bunnies are like smaller and tamer versions of rabbits, who seem adorable but are secretly evil. So like bunnies are from rabbits as rabbits are from, Idk, small mammals?

Seriously though they are different genetically I think. I need to fact check but I'm pretty sure

it's like the difference between a snake and a snek. A bunny is friendly and cuddly and a rabbit is an animal

Im fairly certain that bunnies are baby rabbits. We just call all rabbits bunnies cuz its cuter. There are jackrabbits, and hares they are different.

bunnies are also fatter :L

yes, they're the same thing, although Pirate_melon_ and the_cursed_trainwatcher both had good explanation too XD

Bunnies are cuter. Nothing else I can say could possibly add to this.
