Black cow tail hair is my best guess. I've seen it numerous times and that's what I've always figured it to be. Send some in for DNA testing.
And for the record a 1100 lb cow will get in places that you wouldn't think a rat should be able to get to.
If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
