Milk Carton Bird Box
Simple bird box from a milk carton...
Cut the carton and put the upper half into the lower half all the way.....
Make two slits in the outer part above the carton handle,and thread through a zip tie....
You can simply hang it up like this....
Or to give the birds a little piracy and stop prying feline eyes....go crazy with the duct tape!
Then hang it away from cats and near plenty of cover.....
