Musky the Muskrat

In years past, Musky the muskrat would rapidly swim in the opposite direction if he saw me, but yesterday he changed course, circling the cove to swim closer. When I clicked my tongue as if I were calling a dog, he swam directly toward me -- maybe three feet from shore -- then stopped. When I took a step closer, he slapped his tail as a warning and started to swim away until I clicked my tongue again, causing him to circle back. Has someone been feeding Musky the muskrat? I think he was looking for a handout.
