It depends - are they exact matches and do you like matching? If they're different from each other, that's probably easiest and more on trend.
I began using more than a single animal print thing when pattern mixing really took hold, BUT I usually keep them in small doses if there's more than one, i.e. belt and scarf, or shoes and belt. If the whole shoe is exposed, that's more leopard than a peek of toes from under trousers.
