I’m one of those folks allergic to the hay. The only thing I actually do have an allergy to (great way to find out) but its minor and I persevere through drugs and stubborn love. I hear hay cubes have less of an allergic affect though the cubes don’t prove to be as dental healthy for the rabbits since there’s no long strands for the molars to work on.
Now on to bonding. Some do have difficutlies, some don’t. That’s just the way it is with these wonderful mecurial creatures. People always counsel making it as easy as possible, thus finding a mate through speed dates at rescues and pairing male/female.
Know that you’re already suffering sole cons by not letting them pick and both being male. Doesn’t mean it can’t or won’t happen, or that it will be tough, just means statistically your odds are a little worse.
For my buns who I’m still bonding, they are male and female however I couldn’t go the rescue route and they couldn’t choose each other. I’m 4 months in and while progress is being made, there has been one injury necessitating a vet visit and a few fights so I’m a hairs breath away from calling off the bonding attempt.
My advice if you should go the route is have a back up plan for failure. My plan is that I’ll have two seperately dwelling rabbits so for me its not a big deal. Have a strong amount of patience because it may take time, a lot of it. Be stubborn because there might be quite a few setbacks along the way. Be aloof because at times you might have to let a bit of bullying happen so they can establish a pecking order and someone might get hurt in the process. Lastly be compassionate, which is to say know when its time to call it quits because it might not be meant to work out and if you force it you might succede but at what cost.
Dont let me scare you however, while some aspects of bonding have sucked for me I’ve really enjoyed my time working with my rabbits as a group and have no regrets come what may.
