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”.
@trk @TassieTosser Knox City Council in outer-eastern Melbourne did exactly this: https://www.knox.vic.gov.au/whats-happening/news/keeping-your-cats-safe-and-secured .
The council did it because some of its suburbs (The Basin, Ferntree Gully, Upper Ferntree Gully, parts of Boronia, Lysterfield) border national parks and the Dandenong Ranges.
Younger cats can adapt to living indoors.
But the challenge was with older cats, who are used to roaming around.
The happy medium would be to phase it in over five to 10 years, where any new cats registered or adopted after a particular date have to stay indoors, but older cats can continue to roam.
