Hi all, recently my 7 year old guinea pig has began to lose weight over the past week. Being shes way in her senior years, i was expecting weight loss to happen here and there but the daily small decrease in weight concerned me. I couldnt figure out what was causing it since shes eating her vegetables and pellets just fine. The only thing that could be apart of it being the fact her breathing problems havent been doing so good with this sudden heat wave. But even with her breathing problems, she never lost sudden bits of weight. But, today i noticed that her hay pile was barely touched and i realized that havent had to refill her hay much since the start of the weight loss. I only noticed it this time because she didnt spread it across her entire cage like she normally does and the same, untouched pile still was there. I dont know why she would suddenly stop eating it, but i do know it makes up 80% diet and not eating it could definitely be the culprit behind weight loss. Any tips on getting her to start eating it again? Or even maybe why she would just suddenly stop?
