[2][3] A 2010 study reported on in the New York Times showed that simple buckle collars are actually the safest for cats.

Anti-predation collars may be used to reduce bird deaths from domesticated cats.
[9] These collars may include conspicuous fabrics, colors, and/or bells.
A 2013 study reported on in The Atlantic showed that cats wearing anti-predation collars killed 19 times fewer birds than cats without anti-predation collars.
