"siblings can be kept together"?

[lisab]

No they shouldnt be kept together for ever.

It really really depends on them how soon they need to be split. its normally around 6 weeks that they need to be seperated
I have had girls who at 3 and a half weeks left mum and at 4 weeks had to be seperated and that really is early but mum and babys were just not happy living together.
Where as i had a pair of brothers happily living together untill they were 14 weeks I only seperated them because i didnt want to chance it but there was no sign of fighting (they lived downstairs next to the sofa). but that was the only time with any of my litters. normally 6-7 weeks and thats it.
