Pam Anderson is doing her part to aid victims of the oil spill.

The DWTS alum, 43, will attend a Comedy Central roast of her Baywatch co-star David Hasselhoff in L.A. this Sunday -- but then she's skipping the afterparty to fly overnight to New Orleans and help evacuate dogs with PETA.

Says Linda Allen, the manager at the St. John the Baptist Parish Animal Shelter, "The oil catastrophe has made things worse for many animals, but our shelter, like shelters everywhere, is always full and will be until people spay and neuter."

Urges Anderson, "The real key to both the local and national homeless animal crisis is to spay and neuter dogs and cats and to always adopt—never buy from pet shops," says Anderson.
