Technically, it's not new animals, but it's gendered animals for the ones who don't have, here's all the words:

FERRETS
Offspring: Kits
Females: Jills
Males: Hobs

HEDGEHOGS
Offspring: Hoglets
Females: Sow
Males: Boars

HAMSTERS
Offspring: Pups
Females: Does
Males: Bucks

For frogs and toads, theres' only tadpoles for offspring, (I looked it up and there's no male/female terms)
