BP won't accept Petco F/T?

[TurkeyPython]

So I'm trying to switch my male over to f/t, hasn't worked yet. the last couple times I got the f/t from petco because the local store closed and I don't want to order his size until I know he'll eat them. I always feed my female the ones he won't eat and she takes them no problem, except when I use the petco feeders. Same color, same thawing method, same everything except petco instead of rodent pro.
Might there be something wrong with the petco feeders? I tried offering her one of her usual the day after she refused the petco f/t and she took it immediately. So I know she was hungry.

I had trouble getting my bp to eat but it vanished after using a hairdryer to warm the rats

I'm not too concerned about switching him over, I'm more concerned about my female only refusing the ones from petco. Did something happen to the petco f/t feeders that I wasn't aware of or something?

Well, I've found them to be urine soaked the few times I've bought them. Just gross. I don't blame them for not eating them.

Because they are normally covered in urine I have to give them a good wash down first. I've gotten a few that were mostly bald and had a nasty tumor growing out of them. Those just went to the trash. My ball pythons refuse them, so I can only assume they smell something I don't (and those rats normally smell pretty poor). I've since stopped wasting my money.
