I've been concerned about whether or not he has been drinking the water, but I have been medicating his water for about 23 days now, so he must be drinking it or he would be showing obvious signs of dehydration or be dead by now, wouldn't he? He looks and acts fine other than looking thin. I'm sooo mad at myself for feeding him 2 more times after the first time he regurgitated! I'm still holding on to hope that his problems were just caused by the temperature/humidity/cold draft problems I was having in my snake room at the time this all started. It's seems pretty obvious to me that that must have been what caused my Ball Python's respiratory infection. Either way, Dexter is getting dewormed at the vet to be safe...
