hey guys, need some input/reassurance on a (possibly) fasting BP..

generally my BP doesn't refuse food hes a pretty healthy eater for the little time that ive had him for (6 1/2 weeks now), I was told by the petsmart rep that he was approximately 7 months when I bought him back in march and that he was a good eater there too. hes grown well has been through one shed since. he was originally on mice but I managed to successfully switch him to rats. Usually fed every 5 days but I stretched it to 7 days this week. so last night was his "feed" night but he refused the f/t rat I offered him. he seemed interested by the scent, came out of his hide but slithered right passed it to the opposite side of the tank and back again, stopped and sniffed at it for a good 30 seconds but then just went back in his hide.. I continued to dangle it but he had no interest in it so I left it there for a good hour and 30 checking on him occasionally, everytime I did so he was hovering over the rat checking it out and smelling it but never touched it or he would be craning his neck looking like hes trying to get a better view of me checking in on him.. the rat has been put back into the freezer till Friday when his next "feed" day is supposed to be.

what I would need to know is this a normal thing for BP to do? to smell the rat look interested but then ignore it? is that what they do if theyre fasting? hes still pretty active at night cruising along his cage, temps are where they should be. humidity levels too. according to articles here, fasting is a normal thing for BP's to do, but as a newbie BP owner its worry-some all the same...its the way he sniffed at it and kept coming back to smell it but still not take it made me think that perhaps the rat was "off". it did smell stronger than previous rats of the same batch but is that even a possibility? I think im just a worry wart when it comes to him and I need reassurance that this is infact a normal thing. ( its still pretty early to tell I guess since its only been 8 days since his last meal... )
