Cats and Birds (bugs, pigeons, destructive, New York)

Yeah, I'm sure you're right. It's all those "domesticated" squirrels people allow to roam killing the birds.

Doesn't really matter, they aren't indigenous and they shouldn't be left to kill the native species like the invasive brown snakes in Guam, or any invader species. I love my cats. I didn't choose to have them but they were dumped by human offal in the middle of winter near our place in the north Idaho woods and they're ours now and we love them. And they are safer and the bird population is safer and my neighbors are happier without my two cats out roaming.

Yes they do. Which is why it's important to take precautions with your animals. Our chickens were locked in their coops at night, the sheep and goats were protected by our livestock guardian dogs, and our pet dogs and cats were in the house. Coyotes killing their natural prey doesn't concern me. That's what they are supposed to do.

Removed. My new favorite word.

[mistyriver]

And coyotes aren't the only ones your cats need protection from. Eagles, owls, foxes, RACCOONS, skunks and weasels will all prey on Fluffy the cat. Not to mention bobcats, etc.

Well, I'd much prefer if it were removed to rescue catteries, or to shelters to be adopted out to homes where they'd be properly taken care of. But some people will persist in misguidedly setting cats free and/or allowing them to roam, which guarantees casualties.

Even besides the issue of domesticated cats being an invasive species, and of how they engage in over-predation, when a pet cat takes wild prey, it's often removing calories, vitamins and minerals from the local ecosystem. When another wild animal takes prey, those nutrients remain in the cycle. Everything has to die eventually, but with wild plants and animals, deaths serve a necessary purpose. This is why domesticated animals consuming wild rodents (and other small critters) in the wild can be a problem as well, even though it doesn't tend to upset people as much as killing wild birds does.

This argument would only work if cats were the one and only nonnative animal invading an untouched region and we all know there are thousands of introduced animals, plants, and insects. Everything is changed, the once natural state has long been gone and the once new species are no longer new. There will always be change, it would not be natural for something to never change.

There is an ongoing and constant battle AGAINST invasive species that are destructive to native habitat. We can be fined if we don't keep Russian Knapweed eradicated on our property.

I'm not really sure what your point actually is. If you can't beat them, join them? You don't think it's wise to keep non indigenous species from destroying native wildlife?

"Catteries"?

Mod cut.
