About a week ago I noticed my 9-year-old female squirrel Ruger had what looked like a string hanging from her butt. Within 15 minutes she had passed the entire thing by herself and did not seem in any discomfort. She has been eating and pooping normally other than that. Then yesterday evening I noticed I even bigger something coming out of ruger's butt. Stop this time it took a little longer for her to pass it. I'm attaching pictures. I think it might be a tapeworm but I'm not sure and Im not sure about what medicine I would give her. Thank you in advance for everyone's help!
