Princess & Turbo are litter mates & they both got spayed & neutered @ almost 7 months old. They also got their retained baby teeth removed @ the same time. If you're referring to them 'bonding' as in mating, please get them spayed & neutered to avoid any unwanted pregnancies.
But if you're referring to them bonding together & afraid that they will not bond w/ea of you, no worries! They will adore you & your partner even if you are gone for a min.
