Hello! My little Bo is an Absynian Guinea pig, I rescued her when she was 3 weeks old and left to die at the store. She had a respiratory infection, some antibiotics and eye drops she was good to go. Now she is 4, and stopped eating as of a week and half ago, she rallied back to eating, and stopped again a week ago. She has been breathing heavier, I am forcing water and food into her. Gave her a vitamin d boost yesterday,. Which she seemed to respond well to. I just spent 300 at vet last week. I have no more for this month. She will nibble a little on hay and is taking the mash I made for her. (Cherry tomatoe, cucumber, and mini peppers.) I think it’s her heart because she has consistently been cold over the past week and half. Any ideas?
