Jim Anderson's latest article addresses an extremely important issue that more people need to be aware of, and overall I agree with him (despite my being an avid cat lover and him obviously having issues with them; hence the 10 pound bell comment). But regarding his statement of locking cats up being the "only way to protect birds and wildlife from furry feline hit squads" just isn't true. People, you can leash train your cat! It's true! It is especially true when they are kittens, and possible even when they are not.
My boyfriend and I leash-trained our 2 cats when they were almost 2 years old, and use the harnesses, long retractable leashes, and a trusting relationship between cat and human resulted in them taking to it like water (metaphorically speaking).
Yes, yes, some of you cat owners allow your cats to wander freely outside because you don't like litter boxes inside your home. But considering that outside cats have an average lifespan of only 2 to 4 years, if you truly love your cat and value its quality and quantity of life, as well as the lives of numerous other wild species, then either make your cats strictly indoor or leash train them. Perhaps it will result in long weeks of training, several hospital visits to retrieve stitches, and a couple police visits responding to neighbors' complaints of you torturing your cats, but anyone who has shared the love of a cat knows it's worth it.
