feeding problems

ive had my BP for about 7 weeks. she hadnt eaten the whole time i had her until this past thursday when i finally tried live and she ate it right up. but when i woke up yesterday she had regurgitated it. only the head was digested and the rest was spit up. the mouse was bigger than her body but i was told by a few people form PETCO that if it was a little bit bigger then it shouldnt cause any problems. another reason i heard was it wouldnt digest right if the temp wasnt right. well i can see maybe the mouse was too big but if it was the temperature that was the problem i think she would have went into the warm side of the cage cuz she stayed her her cool side hide all day and night prety much. Does this pretty much pen point that the problem was probably the size of the mouse? and if so am i supposed to wait about a week and a half before feeding again?

thanks

BPs need belly heat, when digesting the rodent, so the correct temps is quite important when feeding, if they can't digest then they will regurge.
I would wait around 1-2 weeks before next feeding and try down sizing the prey, and also have a look at the temps.

What hides do you use?

cool side has a rock hide and warm side has a log hide with UTH

That is most probably why your ball will not go on the warm side, you need a Hide that has 1 entrance 1 exit and is a snug fit, if your ball feels insecure in a log hide because it has 2 entrances and exits then your ball will not go in their.

try and get 2 identical snug fit hides with 1 entrance and 1 exit, this could fix your problem with your ball not going on the warm side.

i have the hide up against the glass so it can only go in and out one side. and the sides are blacked out so it is dark and its a smaller log too. but she normally stays in the rock one all the time anyway

Ye she stays in the rock, because she feels insecure, it is not* their instinct to seek a cold place, unless the temps are unbelievably hot, try replacing your hides with 1 entrance/exit.

what are your temps? cool/hot side

78-83ish cold 89-95ish hot. and can i just get another hid identical to the rock i already have or get 2 brand new ones? the one i have is the yellowish organish one that comes in the 20 gallon zilla pet tank kit.

If the rock is 1 entrance/exit and a snug fit i am sure that would be fine.

How are you measuring your temperatures?

Digital/Dial Thermometer?

Do you have a thermostat?

i have the dial therm/hygr that comes with it and i had a digital one but it broke so i bought two of the individual dial therm and hygr. so i can measure both sides seperately

Dial thermometers can be very inaccurate and your temps could be way off then what they are saying, your hot side could be much hotter therefore your ball not wanting to go on that side.
I would advise you to get a digital thermometer and hygrometer, i am not american but i believe you can get them from walmart for like $12?

Are you using a thermostat?
