Yup, we certainly did - guessing this is a neighbors cat. Seems to always be here and when she is and the chickens catch a glimpse of her, the wracked and commotion that follows is deafening.
Typically, I wouldn't put up with this, however, I'm being tolerant for two reasons: (1) there are only House Sparrows nesting in those bird houses, and (2) we watched this cat catch a wild bunny the other day, which means one less critter eating our flowers. I'm hoping she's also catching other unwanted critters too.
As you can see from the first picture she's very determined to get her some sparrow, as that bird house is some 20 feet off the ground.
