We feed our birds faithfully, and we have many. We also have indoor/outdoor cats. But in spring and summer when the birds are mating and nesting, we do NOT let the cats out because the birds have no chance. But in fall, the cats are out.
She doesn't’t quite know what to do about the birds except chatter at them. She doesn't’t even know how to stalk properly. She just watches them and occasionally runs at them by which time they are long gone.
