The babies at the pet store wereneutered? Are these "Peter's Rabbits?" Ask whatcompany supplies them, and if it's Peter's/Marshall's I would recommendstaying away. They are the same company, and are millbreeders. They've been doing the very young spay/neuter thingwith ferrets for some time now and have apparently expanded it into therabbits they sell. Spay/neuter at the age they must be doingit (8 week old spayed/neutered rabbits!:shock

is dangerous, andnobody knows yet what effects this has on their long termhealth. Most vets won't spay/neuter a rabbit who's sexualorgans are not fully developed. There's been talk lately onEtherbun about Peter's early spay/neuter practice, and several people Ireally respect are highly suspicious. Personally, I wonderwhat the mortality rate is.:?
Anyway, I really don't mean to come down on you, but if you do want oneof these buns then you might want to ask a lot of questions.Ask for vet records, how old were they when they were weaned, neutered,etc. If it doesn't give you a good feeling, then getting arabbit from a good local breeder would be a better way to go.You can see their facilities, meet the parents of your rabbit, and geta really good idea of how the baby was raised.
They wouldn't need to be kept separate once they are bonded (as long asyou can keep Ryo out of the baby's food), but I would take the bondingslow. Let the rabbit get used to your home for a few weeksbefore you start bonding. It's best to keep his stress levellow. I think spayed/neutered rabbits can still go through a"teenage" stage too, so you'll still want to watch out for anyaggression.
