I think about this a lot. Me and Steve often talk about heart bunnies. Chalk is Steve's heart bunny. He adores all the others but you should honestly see his face when he picks Chalk up and cuddles her- it's like he's under a spell or something lol! He wont always admit it, because he feels bad about having a favourite, as much as he loves the others.
I am really close to Dotty, given she adores me and comes for cuddles morning and night, resting her nose on my cheek and nearly licking me to death, and it amazes me how attention-demanding she is, but then I also think of Mouse and how she was my first bunny- I chose her, and of holding her in the palm of my hand on the first day we had her and Chalk. And then I think of how Chalk bonded with us when she was sick, suddenly being affectionate and giving out bunny kisses, and how devastated we both were when we thought we might lose her. And then I think of Barney and how last year after my operation he would let me pick him up and lie down on the sofa and cuddle with me for hours, almost like he knew I couldn't sit up or play on the floor with him. And then I think of Snowy, who as fiesty as she normally is, clings to me at the vets. And at the weekend we put her on the table outside to brush her, and she put her paws on my shoulders and snuggled her nose into my neck for ages, like she was giving me a human-style hug.....
And when I think of all that, I really, really can't decide!
I just can't. If you asked me who I'm closest to, it has to be Dotty, because she's so dependant on me whereas the others have each other and are less people-orientated. But I just really can't pick a favourite!
