Not all my females are neutered
We're working on it
The mum and two daughters have always lived together, never been split and will all be spayed together
My two brother and sister pairs were seperate as they're all related, the boys lived together until they fell out and the two girls lived with mum (now @ Rainbow Bridge)
Boys got neutered but still didn't get on, so after 8 weeks I re paired them with their twin sister. (Four surviving babies-two sets of twins)
My other mum and daughter lived together until they fell out, had mum's son neutered then paired son and daughter leaving mum single
My last three was two boys and a girl, until one male started picking on his sister, so he's separate until neutered, other male and female (brother and sister) still together, Male's infertile
Hope that helps a little bit, its very confusing 'cos most of my buns are related in some vague way
