I bought a few ball pythons. I've had them now for about eight months. I went on vaca an had a friend watch my snakes. 4 days after I came back I fed the snakes. The next day my largest snake was dead. I opened her mouth and saw phlem. Three days later I saw one of the boy snakes with his mouth open and with phlem in it. I put him in a seperate cage immediately. It has been a week today. I was feeding the snakes again when I opened his mouth before I fed him there was a substance caked in the roof of his mouth that looked like a chunk of lard. I removed it with two Q-tips but I don't know if I should bring the snake to the vet or just wait for him to get better. Because I don't know what this substance is. could it just be a cold??????
