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?

Have you literally never heard of what happens when a non native species is introduced to a new environment where it has an advantage?
I guess you also think tumbleweeds aren’t a problem either.
Get yourself checked for Toxoplasmosis.
