They’re not always as cute and fuzzy as the family dog or other standard house pets, but certain exotic pets will surely catch your attention.(19)Though they don’t fall among the ranks of cute or typical house pets such as dogs, cats, tortoises or even fish, the world’s exotic animals capture our attention like no others can. From Australian, where animals like the kangaroo reign supreme, to South America, where the deadly 25-foot snake conjures up nightmares, exotic animals have the power to fascinate. While such animals are not typically thought of as pets, there are growing numbers of those who wish to dispel that notion, or at least ignore it.
    While ownership of some of the more dangerous exotic pets may not be for the clean freak, other exotic animals inspire the same reaction as an Easter chick or a fuzzy bunny.(20)But those who wish to own an exotic pet should do their homework before buying.
    The baby kangaroo we mentioned before, for example, while certainly cute enough to fulfill the role of house pet, can be an owner’s nightmare.
    In the absence of strict training and an ever-watchful eye, a pet baby kangaroo will climb on the furniture, graze on the carpeting, and eat houseplants as if still in the wild—perhaps where they belong. Still, for those brave and patient enough to deal with the adventures of owning any exotic pet, they certainly are out of the ordinary and can serve as both the subject of interesting conversations and a companion that perhaps can rival reliable old Rover.
