Environmentalists have reported the negative impact of red foxes on Australian wildlife. They arrived in the country in 1870. European settlers brought them to Australia for hunting.
However, the foxes began to reproduce rapidly.
As a result, their population in Australia today has reached 1.7 million.
These predators have caused the extinction of 16 mammal species—almost 40% of all animals that have become extinct since the arrival of Europeans.
Scientists have noted that, along with cats, foxes kill approximately 300 million native animals.
Ecologists fear this could lead to the invasion of ag toads or feral cats into Australia.
Previously, scientists have discovered that cats mourn the death of their fellows. Scientists have also shown that cats help people cope with work-related stress.
