my horned lizard is acting very strange. he is just lying down with his eyes closed and not eating. i live in the mid-west and the humidity is high. i know this is a desert reptile and i was wondering if humidity could hurt him. i have had him since the begining of fall last year and this is his first summer in this type of climate. this is also his first time acting weird and up until now he has been eatig ants and crickets very well. is there any special vitamins he may need.
