Neutering male to go with female
Hi,
You can neuter at about 4 months old as long as their testiles have dropped. My 4 month old male rabbit has just been castrated and I am now starting to bond him with a female. I have bonded several rabbits successfully in the past and never had a problem, some do take longer than others but if you do it properly you will be fine. Just don't expect them to love each other straight away, sometimes this happens but other times you just have to give it time.
The best way is to let the rabbits see each other first, without full contact. Either a run, with mesh between and let them see each other each day until they seem unbothered by each others company. Then you can remove the divider for a smalll amount of time and build this up, intervening if they appear aggressive, although remember some mounting and fur pulling is normal initially!! Or, if space allows, adapt their living conditions so they can see each other without gaining contact before introducing them completely. Obviously over the winter, it is much harder to get rabbits out in their runs regularly so you may have to do it another way - such as introducing them in mutual territory.
The way to do this is to put them in a room they have both never been in before, such as a hallway or bathroom and keep a close eye on them while you introduce them. I normally only put them together for a short amount of time to begin with and build this up. You should notice an improvement each time you put them together unless you are lucky enough that it is 'love at first sight'. If you don't, you may need to go back a step and use the run method instead. If you haven't bonded rabbits before, I would say you have better doing it in a run with the mesh between them first, as if you introduce them in mutual territory, it can be difficult to know when to intervene as they are more likely to chase each other and mount as they haven't had the gradual contact like they woud have done in the other methods.
Either way, be brave as it is very rewarding having two rabbits together and a neutered male and female pair works well as long as you give them lots of time and don't rush things when you introduce them, you will be fine.
If space is an issue, use one of the two storey hutches and board it off so both rabbits can be kept separate until they are bonded, as you don't want to be rushing them to live together until the time is right!
