My ham usually weighs in around 130g but for the past two weeks her weight's dropped first to 126g then to 122g. I'm just wondering if this is a seasonal thing/nothing to worry about as she is acting normally otherwise, or whether I need to visit a vet? I obviously don't want to take her unecessarily to the vets but I am willing to if people think it's necessary!
Thanks in advance for your advice!
