Nine people were arrested last week in connection with the "criminal group specializing in stealing and collecting cats", according to the official newspaper of the Ho Chi Minh City police.
Authorities clawed back more than 400 live cats and 80 dead ones preserved on ice, the newspaper said. They seized another 21 cats from a separate facility.
Consumption of dogs and cats is legal in Vietnam, where many restaurants openly advertise the meat -- however vendors are required to obtain certificates showing the origin of the animals.
Police said they swooped on the gang after responding to rampant pet thefts in Ho Chi Minh City, and the suspects confessed to luring and trapping the cats over three years across southern Vietnam.
At least 40 of the pinched pets have been reunited with their owners, Humane World for Animals said in a Tuesday statement, praising police for "decisive action that has saved the lives of so many animals".
