That is simple. Get rid of your cat. (or whatever else is killing the birds)
no it is not
If it fell in your yard then you can keep it.
The Yard Birds
How about a fence around a yard? It does the same thing as a plasma membrane, it keeps the things that are supposed to stay in the yard, in the yard. And, it keeps the things that are outside the yard from getting into the yard. Every once in a while it lets a few select things either go in or out.
Do you want birds in your yard? First organize your yard, have some fruit bearing trees that birds can feed on. also create some mini bird shade for the scorching sun or better make a birds house. Birds love organize yard, which they can live and feed in. Don't forget some water cup or drops for birds to drink. This is like an invitation for the birds, and offering them a free board and lodging. Well well you'll just find out and realize in due time, you already have a bird paradise. Go Green Peace Advocate, protect, shelter, feed some birds in your yard.
Almost half the birds on the planet are abused, by killing them for food or by other birds' predators.
Evil people or cats.
That's creepy.
This keeps happening.
no birds cannot kill house cats but house cats can kill birds Not sure where you got your info from but I disagree. I lived in AZ by the mountains in the city mind you and hawks and owls are well known for killing cats most specially kittens. I know, I had one taken in my fenced back yard. So the answer is yes, birds can in fact kill house cats.
Use a bug killing chemical.
