I actually posted this to remind people how important the hide is. He really refused to eat because i took his hide away. As soon as i gave him his hide back he ate again. My boa is 5 foot now and usually on large rats (300 grams) every two weeks. I fed him last 2 times jumbo rats (around 400 grams) because i feed live. Let me explain, when i go to buy a rat for him, i don,t weigh it at the shop, i do that at home. At the shop i have to use my eyes to evaluate the rat size. When i get home i weigh it before feeding it to him. As to be expected, sometimes the rats that i buy are bigger than i wanted. By the way, between the last 2 jumbo rats which he ate, there were 3 weeks time. I did not advice anyone anywhere to feed like me. I always adviced people to feed less than me. If someone has 5 foot boa like me, i have adviced to feed it medium rats. This was my advice to other. I usually upsize the food of my boa if he remained hungry after eating.
