I have no idea what the swelling is . It is still somewhat there but its not red or hot to the touch like fever . He still has no fever and he is eating all on his own now . He is pooping all normal . He is pretty active and even comes to sleep outside of his house now . He is looking so much better than he did last week at this time. I am still keeping a close eye on him . I do have one question about the yogurt . Is it ok to give that to him daily or should I cut back?
