The first week you will want to keep them separated to allow her to help heal.
It usually takes about 48 to 72 hours for females to really start to perk up after the procedure. She most likely will not want to eat once she gets home and the best thing is to not fuss over her and just let her chill out…she will be recovering from the pain meds and the anesthesia. You may notice some mushy poops as well due to the meds, so don’t be alarmed about that.
Make sure the vet gives you some pain medication to take home – it’s usually 2 to 3 days worth.
After a week, I think it would be find to do the short 15 minute interactions as long as she seems alert and acting normal. Many times owners will find their rabbits to be more “hormonal” after the procedure for about a month and that’s normal as their body is adjusting – much like menopause I suppose.
I’m glad you made the appointment to get her spayed :~)
