I don't think the hold is pressurised, and so there would be very little oxygen there.

  Where do pet crates go? I think it might be.

  Cargo holds are typically pressurized. Pressurizing forward of the aft pressure bulkhead doesn't really add significantly to the structural requirements of an aircraft as I understand it. Furthermore (in addition to pets) you'd probably see lots of leaking and otherwise damaged contents of luggage/cargo if the hold were unpressurized.

    More than that, the most efficient pressure vessel is a circular section (tension only). Making the floor of the passenger cabin the pressure vessel would be very heavy, as it would have to carry the load in bending.

  Of course it is pressurized. If it were not shampoo and toothpaste would leak out of their containers.
