I wonder that too! but yea when these pic were taken he was not eating he didn't eat for like two weeks straight maybe more i noticed it was not that he was not hungry it was because he had a problem with his tongue getting stuck and hanging out so i got him sum good multi vitamins had to force feed once which i will never do again cause i felt so bad but after that he has been a eating,stalking,lunging crazed eating machine his weight has gone up drastically same with the growth over all i really was afraid that i was gonna loose him but surely enough a little TLC took care of him and i got a little monster on my hands now
