about this time last year my baby(well he is about 4 but i've only had him 2 years) went in to burmutation for the first time sense i've had him. at first is scared me a bit but he came out of it ok, except he was a good bit thinner. all summer i've been trying to get him back up to a healthy weight but he just doesn't seem to be gaining. i've had him checked for parasites and he is clean. he is acting like he is going to do the burmutation thing again this year but im worried he is to thin to do this and be healthy. what can i do?
