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”.
Cat numbers go up, native bird numbers go down, you can’t explain that.
Also the article is about Australia. Sorry your American brain can’t handle that concept.
Its a global problem. Its been best studied in North America, so I use those studies.
