The ministry ordered a surveillance and rapid-response team to investigate the deaths in tambon Wang Kham, Khlong Khlung district. The investigation ruled out rabies as the cause.
A veterinarian said the deaths were likely to have been caused by the feline panleukopenia virus (FPV), which is a leading cause of cat deaths.
The affected cats were reported to be listless, unable to eat, and prone to vomiting before they died over the past two weeks.
