So we took the box off, removed the tree and that was that. But I did take a picture of the inside... so sad. I bet it was the fault of that pesky cat that is not only using my flower beds as a toilet, but also killing everything in sight in my garden! It's relatively new to the area, and I found bodies all through the summer last year - even a big crow! It doesn't just go for birds - I've found a mutilated frog too... I did keep the hose on standby for a while, and I WOULD have hosed it if I had seen it stalking.
