"Help protect native wildlife. Every year free-ranging domestic and feral cats injure and kill millions of wild animals, especially song birds. Please consider keeping cats indoors. Cats kept indoors live longer, they are less likely to contract disease and parasites, they are protected from traffic, and they are protected from urban coyotes that will catch, kill, and eat cats.

"Each year at least 60% of the wildlife we admit to our Centre have been caught by cats."
"Cats account for almost three quarters of non-natural bird deaths."
