We can't! Thats the thing. For one, teh vets closed at 4 today and another is that we can't take her in because we are leaving for 4 days. My parents said if we come back and its still there, we will get it checked out. In th meantime, if it keeps getting bigger and bothers her, then my sister, who is watching her(shes 23) will take her in...we will have to wait until then!
