Komatsu has stood down two workers after discovering photos of the men at the Welshpool workshop holding cats.
The photographs, which were found on Facebook, show workers holding up what appear to be dead cats.
The caption on one of the photos reads: “A cat we caught on our recent hunt around Komatsu grounds”.
Another image shows a man who is not affiliated with Komatsu holding two black cats by the tails, with a caption that reads: “taking care of the ferals”.
A comment on the photos suggests one of the cats was disposed of in a recycling bin.
Komatsu general manager for people and strategy Colin Shaw told The West Australian that two Komatsu employees involved, including the worker who took the pictures, have been stood down pending investigation.
