I have a squirrel that I been feeding for 3 years I call her Brutus. ( That was before I knew she was female. Brutus had babies this year right around the middle of april she is avery happy squirrel and very healthy she eats walnuts,pecans,peanuts,sunflower seeds,pumpkin seeds, and bread. About two weeks ago I notice a bump on her back and it has now grown to about the size of a walnut. It hasn't stopped her from eating, It doesn't appear to bother her but I can't tell. Her are some pictures maybe you can tell what it is. I want her to be healthy I love her so much. Can she survive this? Hope to hear from you soon.
