I know there are a billion threads on this but I can't seem to find what I'm looking for so I'm starting a new one. I know that it is common for balls to go off feed this time if year. I have a 3 1/2 year old female that I adopted last April so this is my first winter with her. She has eaten consistently since I got her I feed her a med rat every two weeks. The question I have is how often should I offer food to her now?
