(Cover) - EN Showbiz - Holly Madison is stocking up on woolly sweaters for her pet ferrets in time for Christmas.

The former Playboy playmate is concerned that her unusual house-kept creatures stay warm as the winter months draw closer in America, where the blonde-haired beauty lives.

Holly is currently shooting her reality television series about her life called Hollys World in Las Vegas, where she said the temperatures are quickly dropping.

It has made the 30-year-old anxious about the welfare of her furry friends, which she received as a surprise gift delivered to her doorstep.

Ordering some sweaters for my ferrets, she divulged to fans on her Twitter page. Vegas winters are cold! (sic)

Holly, who has also appeared as one of Hugh Hefners girlfriends on the reality television series The Girls Next Door, is well-known as an animal lover.

She owns a pet Pekinese dog named Napoleon who has blonde fur and brown eyes so it matches her, but the model had not anticipated the addition of ferrets to her pet brood.

Umm... Do ferrets and dogs get along (sic)? she recently wrote on the social networking website. (C) Cover Media
