I had to stop feeding the birds, not because of Bears but rats. Whilst doing my yoga in the sun room a couple months back I saw moment at the feeder and went to look and Holy cow, three very large rats were eating breakfast. Freaked me out, I hate rats. Screaming loudly I tried smacking the window, nothing- I got the dog to bark they just sat at the feeder looking at me and I swear one of the rats gave me the finger. I moved the feeder closer to the neighbours property, I bought the house five months ago and I figured the rats were older than five months ergo part of the hood so the neighbour can keep them.
