Initial tests on the carcasses of 33 cats dumped at a temple in Songkhla where they were then killed by dogs have shed no light on why the animals were so helpless.
An activist at Ban Mah Yim, a dog rights group, said tissue samples from the cats were sent to the 12th medical sciences centre for testing, to see if they had been drugged. Nothing unusual had been found.
Pol Lt Col Kanthaphon Chaetipattananakul, of Kho Hong police station, said they were trying to trace a pickup truck seen dropping off 36 cats at the temple in Hat Yai district, Wat Thung Ngai. Finding it would help show who dumped the cats and whether the animals were drugged before being savaged by the dogs.
