And there’s other reasons to discourage cat ownership..
Predators are disappearing world-wild, including from our seas. On land this can have unforseen effects. The left diagram below is what we have done, and the right is what the science suggests we should do. The problem is these decisions would effect on-farm income.
However agriculture and conservation can work together. Rabbit hemorrhagic disease virus in arid South Australia released 4 threatened study mammals from feral predation. The result was the 4 species’ removal from the IUCN Red list.
So next time you see a spider or cockroach in your cupboard remember your own actions and decisions also have consequenses.
