What age do they start this usually? Is it the same as normal (around 8-9 mos), or is it earlier because other males are around? I've got a pair of boys. They, as well as the litter's only female, are scheduled to be fixed the day they turn 5 months. I will seperate her from them when she turns 4 months (vet advised to be abolutely sure they dont knock her up). is this age too late to avoid spraying/ agression?
Any helpful answers appreciated.
