Wiener rats?!?! LMAO......I think you meant weanling. Thats too funny!

Its not uncommon for BPs to fast for long periods of time with no harm to the animal. I house all of my BPs individually, that way I don't have to worry about them stressing each other out.....it may sound funny, but you can give them too big of a cage and this can stress them out as well. BPs are shy, seclusive snakes and are easily stressed by things like this.
