We live on Mobud and have always enjoyed the squirrels. We have 3 squirrel feeders which we keep filled with sunflower seeds. Within the past 2 weeks, every squirrel has disappeared. Every morning I take a mile and a half walk around the neighborhood and do not see a single squirrel. I am afraid someone is killing them. If this is so, is there something that can be done? Does anyone know what is happening to them?
