After looking at some photos on google, I’m worried that my guinea pig is dealing with impaction. His bum has looked like this for as long as I can remember and when he got a full body exam at the vet she didn’t mention it at all so I never thought anything of it until this morning when I noticed he has lines going down the middle of his poop and one source said he could be dealing with impaction. If he is what is treatment like for this? is it an emergency situation? (I have been texting with his vet but I cannot make it to an appointment at this time) also can someone tell me how to attach photos to my thread!? i just made my account, thank you!
