Pet's info: Small Animal | Unknown - Small Animal | Male | unneutered

My guinea pigs zues and zios (almost a year, both boys) have recently been having really weird stools. I looked up this and it doesn't really fit the "diarreah" stool, it looks a bit different. But surely not normal for them, i really want my piggies to be happy and healthy and really need someone for free to help me get the help and answers I need as i cannot afford much right now..

A diet change or addition of new fruits/veggies or treats can affect the stool in guinea pigs. A veterinarian can run tests to rule out gastrointestinal parasites or a bacterial overgrowth and perform a physical exam to make sure that your guinea pigs are not dehydrated, are in good body condition, do not have maloccluded teeth, etc. However in the meantime I would recommend ordering Oxbow critical care overnight from Amazon.com or finding it possibly at a local pet store, mixing with water and syringe feeding plus offering it in a bowl in addition to their regular chow for ay least 3 days. If you don't see an improvement in the stool, I'd recommend calling around for lower cost options such as veterinary care from a local ASPCA, etc.
