Feeding Issues?????

[ccarr1]

So i've tried feeding my 3 snakes yesterday. None of them wanted anything to do with them.My question is this; they haven't eaten in about 2-3 weeks( bp,corn,bci).I live in pa and it's winter(well kinda) do they go into "hibernation mode" and that's why there not really interested in food right now.I cleaned out there cages while i was trying to feed them and they act like all is well when put them back in there cage. Is this something that i should be concerned about or should settle my emotions down a notch!!!! :jawdrop: Any input would be greatly appreciated!!!!!!!
