Breeding Season = Feeding Problems???

[ballpython5000]

As most of you may know by now about 2 weeks ago i got a new ball python. Now this thing still has maybe a foot or so to grow. when i bought it the guy said it had not eaten in 30 days. understandable. it had been in a cage with 2 other large balls. and it was a 30 gallon. heating was less the it should be. but over all the snake was in awsome condition. so i got it. its all find and look perfect. acts perfect. a nice thick body with nice tone. but it wont eat!!! i have only tried rats and mice. and it is totally not interested.
can this lack of feeding maybe be becuase of breeding season? i hear they regulary go off of feeding at this time. first time this has ever happened to me. i know it has only been 2 weeks. but the pet store has another one of almost equal size that i know is the perfect feeder. it bites at any and everything. i dont mind a bitter as much as an anorexic snake. i know that if i hate problem feeders that ball pythons arent my best choice, but besides that i love em, lol. so should i go to the store and swap snakes while i still can? or keep the one i have and pray that it is becuase of breeding season? any advice is appreciated. thanks
