Hey everyone, about a week ago I noticed my 4 1/2 year old guinea pig felt much skinnier and had some crust on her nose and eyes. She was eating normally but I still made an appointment with the vet and they said her lungs sounded clear and didn't see any obvious organ failure happening. The gave me meloxicam to give her for 7 days and some ofloxacin solution for her eyes. She seemed good for a day or two and now she feels skinnier than before. I don't have a gram scale and don't weigh my guinea pigs weekly (sorry I know I'll start doing it asap). She still is eating and running around the cage but I feel this is the end for my piggy, as I had one with similar issues who had a stroke of some kind and died in my arms last November. I know she is older and this is common in older guinea pigs to give out as they approach 4-6 but I wanted some advice if I should do something different.
