One of my rats passed away about a month or so ago, and my remaining 1 year old rat is now without a cagemate. I thought 2 new baby rats would be a good idea, instead of one, in case Sadie is aggressive at first, then the brunt of it would be more balanced, as 2 youngsters vs 1 adult. The other reason was so that once Sadie passed, the other 2 would accompany each other for their last years of lives. My mom, however vetoed the 2-baby idea, and now I am stuck. Do I get a single baby and hope for the best, aggression wise, then rehome it or get it a senior buddy once Sadie dies? Or do I continue to persuade my parents to let me get 2? I do not want to continue the costant cycle of rat ownership forever. Any advice is greatly appreciated!
