Boa wont eat hes been lost for 2 months

[danthony428]

okay about 2 months ago, our red tail escaped, we presumed him dead seeing that the house is also full of cats and dogs and a codamundi, i finally found him last night, he was so cold, and kind of pale looking, today we went and got a mouse for him to eat, and he went ahead and constricted it and killed it, but its been about 3 hours and he still wont eat it, now I've been reading about shedding and how they sometimes don't want to eat when they're about to shed, and i haven't found any skins around the house, so i figure hes about to shed, is this why he wont eat or is there something else i need to worry about, the reason I'm worried is because i don't know if he's eaten anything since he's been missing, and I'm so in love with this snake i don't want him to die, please help!!!
