Without digging out the invoice (which is at home) i can't be sure but I'm pretty sure if was at least 3 weeks if not 4....the vet said that he should be completely sterile after about 2 weeks but we held off a bit longer to get the kitchen sorted.....
Atm he's too bust munching to pay her much mind, which I think she's quite enjoying. I'm inclined to hope that it's dominance mounting as opposed to sexual because he's only doing it when she tries to have a nibble at some hay or sit in the cage.
Thats good he is letting her rest, yes I thought dominance mounting as opposed to sexual aswell, just got the impression it was full on which can be a bit tiring for the doe - is she eating alright etc?
A male is fertile for up to 6weeks after the castration.
