Keep a daily or weekly behavior log for you pets. Every 2 weeks we have a "Ferret Day at the Spa" where we trim nails, brush teeth, clean ear and weigh each ferret. This is also a good time to fell around for anything unusual. The weights and other relevant information is put in a spreadsheet which allows us to compare weights over a period of time. This includes seasonal weight loss etc. The daily logs monitor medications, behavior, events from the day (like annual vet visit), eating habits and anything else unusual. We have an Insulinomic ferret and this way we are able to track Prednisone dosages, weight, amount of food he is eating and episodes. It has been really helpful. I also think we should collect and post a summary of tips somewhere...any ideas? Ailigh [Posted in FML issue 5216]
