The tiniest squirrel I’ve ever seen showed up in my backyard the other day. He/she is doing squirrelly things..climbing up the big oak tree, digging and running around. He/she mostly stays under the bird feeder and picks up whatever falls. I’ve put out some sweet potato bits, avocado bits and apple. It doesn’t seem to be interested. I have noticed it drinking water, which is important. Any suggestions of what this baby may like to eat?
