Today I took out my gerbil and i noticed that she had red spots right next to her nose which appeared to be blood which were easy to spot cuz around her nose is white. I have no idea how her nose got bloody. It doesnt seem to be bleeding anymore, but i dont know what to do should i leave it alone?! This is my first gerbil, so I am not quite sure what to do. I need your advice
