The neighbors of Fukuyamain western Japan, are ordered to notify the authorities if They see an “abnormal looking” cat. The reason? The entry of a feline into a metal plating plant, a moment that was captured by the factory’s security cameras, reports The Guardian. But not only that.

A factory worker came across a trace of yellow paw prints. The clue came from a container of hexavalent chromium. This compound “has beneficial properties, such as corrosion resistance, durability and hardness.

They are used in the “manufacturing of pigments, metal and chrome finishing, stainless steel production, leather tanning and wood preservatives, as well as in dyeing processes in the textile industry, printing inks, drilling muds, fireworks, water treatment and synthesis of chemical substances,” explains the National Cancer Institute of the United States. “Occupational exposure to these compounds is related to a increased risk of lung cancer and paranasal sinus cancer and nasal cavity,” adds the aforementioned source.

This chemical can also reach cause respiratory problems and skin inflammation, which is why the authorities raised the alarm. On Tuesday, the feline still did not appear. In fact, the possibility is being considered that he died after coming into contact with the chemical.

While it is true that there are no images that prove that the animal entered the tank where the toxic liquid was stored, the company said that part of a sheet that covered the tank appeared to have been turned over. The only thing seen in the video is the animal leaving the factory.
