We offered to foster a very young tortoise ready to have kittens. Day before she had then she became very sick w upper respiratory infection. She had 4, one died. Vet gave her antibiotic and steroid shots. Kittens nursed well until 3 days old, then they each became sick. Vet gave micro shot and gave us shots to give them for 5 days. Mama seems unable to nurse. Why would she stop having milk? We are using kmr w 2 but one still tries to nurse and refuses milk replacement. They're all slowly getting better. Is there a way to restart her milk flow? Sorry so long. This has become exhausting. Thx.
