From the list below, select all of the quadruped mammals that might be found as a pet in a typical American family home.

To determine which quadruped mammals might be found as pets in a typical American family home, we first need to identify common pets that fit this category. Quadruped mammals are animals with four limbs. Based on commonly found pets and the list of quadruped mammals, we typically consider the following options:

1. Dogs: One of the most common pets in American homes, known for their companionship and loyalty.
2. Cats: Another popular choice, cats are often kept for their affectionate nature and independence.
3. Rabbits: These small mammals can be kept as pets; they are gentle and can be litter trained.
4. Guinea Pigs: While technically not quadrupeds in the traditional sense (since they have more of a squat body), they are often included in pet discussions due to their four limbs and are popular among families.
5. Ferrets: Although they are not dogs or cats, ferrets are four-legged mammals that can also be kept as pets.

Less common pets that might also be considered include pigs, chinchillas, or even some breeds of small goats or sheep, but these are not as typical for family homes.

In summary, the most common quadruped mammals that can be found as pets in typical American family homes are dogs, cats, rabbits, and guinea pigs.
