I bought my Columbian tegu about 2 weeks ago from a reptile show and he has ben doing fine until today when i went to take him out of his cage. His legs, toes, lower back, and base of his tail were twitchin and so i just left him in the cage and kept an eye on him then he started to open his mouth and his tounge would hang out and it seemed like he couldn't get it back in his mouth. this happend twice today and it worried me . If anyone cant help that would be great, thanks.
