A pet carrier includes an outer frame and an inner frame slidably coupled to the outer frame along an axis. The inner frame defines a pet compartment. An energy absorbing element is disposed between the inner frame and the outer frame along the axis. During a vehicle impact, momentum of a pet may move the pet toward the inner frame and may force the inner frame to slide relative to the outer frame. During this movement, the energy absorbing elements may absorb energy from the pet, softening the impact of the pet with the pet carrier.
