Post neuter

Am I remembering rightly that it's 6 weeks post-neuter that a male is still fertile? Or is my sleep-addled brain getting muddled?
I was sure it was six but thought I'd double check and the RWF guide says 4 weeks - which would mean I could start bonding today (handy as I'm moving bedrooms next week so it won't be safe for Ben to stay indoors but would save him moving back out on his own)

I think some people say 8 weeks, to be on the safe side. If he is going with a spayed female then I think it can be done sooner if his hormones have died down a bit already. Good luck with the bonding

I would play safe and say 8 - I'm sure Jane once mentioned a boy still fertile at 6wks?

Is the RWF page wrong then? :?

Bump - would be interesting to know if the RWF is giving out incorrect advice which could lead to more accidental pregnancies :?
ETA: The Rabbit Rehome page says 'up to 4 weeks' too
