We recently lost the older male,,,,the younger male (about 10 months old) not neutered, the 2 never lived together,,older fellow was dominate. Young rat seems to miss the older.(They did share a common play area) We wish to adopt/ re-home 2 rats. The question is , should we try and re-home older or younger rats? Example,,,came across an ad for 2, 5 month olds..needing a home,,,almost jumped at it,,,clear the 2 are bonded to each other,,,and are they bonded to the present owner? Would they take to a new rat and owner? Or start fresh with 2 new pups from a breeder,,because the pups may not have any attachment to owner,, and the transition may be less stressful,,Please give me a moment...adopting an older pair, means they have to gain our trust, then the resident rats'....versus 2 new fellows who could probably introduced pretty soon to the resident,,can some body give me help?
