Set-up a ground-level  feeder in your backyard, and make sure there's plenty
of stalking aids (like tall grass, medium-sized rocks, etc.)

That should allow both birds *and* cats to feed... safely.

Heck, you would be just helping mother Nature along, right?

Put the bird food up high, on a table or hanging from a tree in an
exposed area so the birds can see the cat coming early.  You can also
put a bell on your cats collar so the birds can hear him.  Your cat will
also help to keep the rodents away that are attracted to the fallen bird
seed.

Balance of nature.  Heck, where I live, there are birds that can eat my
cats.
