Hi!
I am a new member and found your site by searching for rats and birdfeeders on Google. I am very happy to have found this nice forum. Here is my advice...I live in NW FL and have multitudes of squirrels, opossums, raccoons and other varmints to contend with when thinking of feeding the beloved birds. I have tried a variety of feeders and become disgusted at how they do not deter the pests as advertised. About 10 months ago I purchased a Rollerfeeder online and it has changed my entire yard and birding experience! I know that this forum doesn't want ads, but this is more of a testimonial for this amazing feeder. I won't go on and on, I just suggest that you google Rollerfeeder and go to their site and read it for yourself. The squirrels have completely given up on even attempting to eat from it and I think it has paid for itself in birdseed savings! I mention this specifically for the people who posted on this thread about being frustrated with their feeders and the man who couldn't have one at his condo due to rats. This feeder keeps all unwanted animals out, even large birds. Hope this helps and thank you for your other rat suggestions for the rest of my yard!
