Yes, my Rory is definitely my heart bunny. I can't help it! I love ALL of my bunnies and treat them the same, but it's absolutely undeniable that I love him the most. I don't have a second favorite or third favorite or anything, though.
For me, I'm certain that Rory is my favorite simply because of circumstances and not really because he's objectively more special or better or anything. We adopted him in October of 2007. He was my first bunny since my childhood bunny (Cinnabun) had died several years earlier. I had several months to bond and fall deeply in love with Rory before we adopted little Tallulah in early January 2008, so just a little while later. She was so cute and sweet and I fell for her very quickly. Within a month or two, I loved her just as deeply as Rory and Cinnabun. No more than them, no less. Then she died in May of 2008 at just 7 months old and her death changed everything for me when it comes to bonding with and loving pets. She was so young when she died (Cinnabun died at 7 years and had led a full, happy life) and I was devastated. I simply haven't been able to love any other bunny (or cat or bird, not even the bird that I raised from an egg) anywhere near the same since she died, I think as a method of protecting my heart. My love for Cinnabun, Rory, and Tallulah is/was all encompassing and so very deep.
My other bunnies came along after Tallulah's death and I'm certain that's the only reason I'm not as deeply in love with them. If she hadn't died the way she did, I'm sure things would be different. I wonder if I'll ever love another pet as much as my first 3 bunnies. And like I said, don't get me wrong, I DO love my other bunnies- absolutely and unquestionably- it's just not the same, which honestly may be for the best and healthier. My husband dreads the day Rory dies because we both know I will be utterly inconsolable for a long time. Tallulah died almost 5 years ago and I still tear up when I think about her. 2 more of my bunnies have died since- the wonderful Skyler and Nomi- but she is the one I'm still mourning, though of course I certainly miss Skyler and Nomi a lot, too. The fact that Rory will be 6 years old in a few months is very distressing to me because I can't bear to think of him getting old and dying. The earlier birthdays were all about fun and celebrating another year, but now they're scary (though he still gets a present and cake and special bunny treat for his birthday).
Let me reiterate once more that all of my bunnies are loved and spoiled very much, I'm crazy about them all and think they're all amazing, and Rory does not get more attention or anything than the others!
