rich as i said earlier different snakes eat different ways, the other poster says i am power feeding but it i do not believe i am. i have had burms and retics all my life, i have had great results and have fed then according to how they want to eat...my larger of the two sibbling female sri lankans eats much more than her sister..but her head is larger and her processing of her food is also faster...so even though she is a sibbling she is still different from her sister. the smaller female eats 2-3 jumbo rats every 2 weeks...while she eats between 5 and 7 depending on how actively she hunts the cage. , they are both growing great and as these are my first 2 sri lankans i am watchin carefully their growth and eating. they are having great sheds, and the vet here has been amazed about the coloration and health of these girls. my male has had times where he has gone 5 months without eating...i too have wasted a lot of cash trying to feed when he isnt eating but these guys are moody so when he eats i am happy, when he doesnt watch for things like RI, and other problems..then i consult the vets . so back to your burm...he sounds perfectly healthy for the avereage burm, 8-9 feet, 30 pounds..that is good... i will try to post some pics of my "overfed sri lankans on here in a day or two..i am tring to figure out how to do the pics thing here..and ill send a pic or rameses..my 16 1?2 foot male..5 years old and perfectly healthy!...if i can find my old pics from when i used to breed back in the 80's ill show ya my 19 year old, 26 foot female..my god was she a hottie!
