Well, the Kestrels might harass a cat near it's nest but the little falcons and small owls aren't big enough to kill a cat. They eat mostly mice, lizards, grasshoppers, crickets, and small birds. I've seen Kestrels kill starlings several times. Barn Owls probably wouldn't tackle an adult cat, but Great Horned Owls will. It's common to find cat skulls under Great Horned Owl nests, and along the Front Range domestic cats comprise about 5% of the typical Red-tailed Hawk diet. It's a dangerous world out there.

I sometimes get wasp nests in my bird boxes, but I'm hell on wasps with a blow torch.
