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”.
Foxes are also introduced, so I’d say cats everywhere are “better” because there’s half a chance their numbers can be reduced through requirements for owners to contain them.
Also, cats can be baited too if required. And, IMO, it is at the point where it’s required.
