I saw that little Finnegan, how cute.
Years ago somebody found a nest on the ground with 3 little black squirrels, still with their eyes closed. The nest came down on a stormy night. I took them in and fed them with a formula from the vet with a syringe every 3 hours through the night.
Two of them did not make it, but Picasso made it. He always sat on my shoulder, I went out, he did not jump off. I was the tree, the mother, and all he had. It was interesting to see him grow. He was so naked, the tail was just a string. Slowly he developed into a cute squirrel.
Later I gave him to a wildlife refuge where he learned to look for food for himself. I still miss him and would love to raise another one.
