Sadly, Krista fails to make any arguments to support her opinion. She simply states "A declaw prohibition ...... would affect the lives of some cats for the worse."  
No stats, links or peer-reviewed scientific articles describing how banning declawing would affect cats for the worse.
Could it be that pressure from veterinary groups that have vested financial interest in avoiding a ban is getting to her?  This $1 Billion industry has a strong lobby and will bully anyone attempting to curb this profitable venture.

Much research exists Krista, google it and then make calls to shelters in those cities that banned it to find out what their experience is. Or you could research any number of countries in Europe, Japan or Australia, to find out that a ban has existed there for a long time and no negative effects occurred.

Fact is 5000 newly declawed cats are worse off every day in the US.
