What happened to Algerian cats?

From ANIMAL PEOPLE, March 2003:

HOUSTON–Members of the Houston Animal Rights team and PETA
picketed the Houston headquarters of the oil exploration firm
Halliburton on January 12 to protest the alleged poisoning of 200
feral cats at a remote work site in Algeria.
Former Halliburton employees said that the Halliburton
construction subsidiary KBR, Andarko Petroleum, and an Algerian
subcontractor brought cats to the site to control rats, but failed
to sterilize the cats before releasing them. The cats were poisoned
after Halliburton withdrew from the project. The demonstrators
argued that Halliburton had a moral obligation to ensure that the
cats were treated humanely.
Reported KTRK Channel 13, of Houston: “Halliburton issued a
statement saying its company left the work site before the cats were
killed. Andarko said the Algerian company brought in the cats and is
working with the Algerian government to remove the animals in a
humane manner.”
Halliburton employed U.S. Vice President Dick Cheney
immediately before he agreed to become running mate of President
George W. Bush in 2000.
