We live in an apartment building, and to keep my cat entertained, I started putting bird seed on the windowsill. In 3 weeks we have like a dozen who come by to feed. So my cat is on the lookout for them all day long until after sunset. Yesterday they got spooked and I havent seen more than one bird visit us today- and my cat looks so disappointed. His eyes have started to dry a bit cause he is constantly out the window. I know the birds will eventually come back, it is all good food. But is this something i should continue with? My cat shows no aggression, and by evening he is tuckered out. So no more random zooming around the house. Have any of you gotten a bird house or something similar for the cats to watch them and be entertained?
