feeder size / poop, pee and shed schedual

so I have now had my BP for a week and have fed him (could be a her) twice both times he ate a 15g med feeder mouse about 3in long. I want to try rats and want to know if I should buy pups or weans he is 529 grams today before I fed him. I also have no way of saying home to receive the frozen package how urgent is it to sit in my apartments office before I get home?

How often should he poop, pee, and shed? It kinda worries me that he has not pooped or peed the full week I have had him.

If you're BP is 529 grams, he should be eating much larger prey. It's supposed to be 10-15% of your BP body weight so you should be feeding 80 gram prey. If it's cold where you live, it might be okay to sit a little while outside but you'd want to get that package into the freezer within a few hours at the most.

BPs don't really have a schedule when it comes to passing or shedding. I've had my BP for a month and he's only pooped and shed once. Time between poops can take weeks or months, your BP will pass when he needs to. If you see he's constipated (big mass by his tail that seems stiff), he might need a warm bath to loosen it up and help him pass but otherwise leave him alone and he'll do it when he wants to. Shedding is the same. It can be as little as weeks or as most as months between sheds. As long as you keep the humidity right and don't notice any failed/stuck shed then he's fine.

Oh no! okay I will go to the store tomorrow an buy the proper sized feeders... Should I worry about going straight to small rats 40+ grams each?

Well I wouldn't feed a live 40+ gram rat so personally I'd get him eating f/t first but I'm more inexperienced than others on the forums so you might want to wait on their opinions

Well he is already on F/T mice I just don't want to feed him anything to big... I don't mind feeding him multiple in one sitting I guess I just need to know where to start.

If that's the case then that's fine if you try and feed the larger prey size, I'd just be worried he wouldn't take it since he seems to be a mouser. It'd be best to find a larger prey size that's still not wider than he is at his widest point. Maybe you can move up in mouse prey first, then switch to a rat of the same size later to have a better chance that he'll switch for you
