So I called the vet yesterday and she wasn't in until this morning, but I had talked to her tech who said if she's otherwise acting ok eating and drinking it could most likely wait until she was in because the other two vets only see dogs and cats. So she called back today and said that TMS suspension which I already have should be safe to start her on with the babies and that there are a few things it could be such as UTI, some sort of complication from birthing or other infection. And since then all her pee has been seemingly clear? So would you start her on the abs? I'm cautious, if its not necessary, of giving it to her while she is still nursing. But this is the first time I've ever had a rat with blood in their urine and the first pregnant rat I've owned lol ,so I'm torn as to what the best decision is?? Thanks again everyone! Meanwhile the babies are getting so big and playing alllll the time =) Will post some pictures tomorrow
