Angier,

Be careful of who you transport.

Here are some pic's of American's 757 where a Pit Bull recently escaped from his kennel in a cargo igloo in the forward bin. The dog did some serious damage causing American to establish a new policy of not accepting animals of any kind with the potential of doing this damage. After the dog chewed through reinforced fiberglass he chewed through wires And the flight subsequently lost TCAS , both ATC transponders and a VHF/VOR receiver.
