Broader adoption of keeping cats safe at home would have large benefits for cat welfare, human health, local wildlife and even the economy. So, should cat owners be required to keep their pets contained to their property?
The answer to the question is obviously “yes”.
Then why add cats to the pressure the local fauna are feeling?
Let’s take what you’re saying about dead zones as true. Somehow birds still come by to visit local bird feeders etc, in spite of how much negative pressure we Hunan’s are causing. Add a well-fed apex predator into the mix, far from its native homelands in Egypt. How is that fair to local flora and fauna?
