An access portal for a pet carrier allows a pet owner to insert a hand into the pet carrier but prevents the animal contained therein from escaping through the access portal. The access portal may be blocked by an elastic barrier with an aperture that stretches to allow the pet owner to gain access to the interior of the pet carrier. Doors covering the access portal on the inside and/or the outside of the carrier may also be used instead of, or in conjunction with the elastic barrier.
