I have a mini lop, and she is easily the sweetest bun I've ever had. Very affectionate and cuddly - but then again, I could have just touched lucky to be honest, I certainly feel it. Had a french lop in the past, she was sweet, not a bad bone in her body but just more nervy, on the other hand, the other small lop (though not quite mini really) I had at the time was super cuddly as a youngster, but turned out to be an absolute horror. Then again, these were outdoor buns whereas Autumn the mini is indoor. Micky, my late bun (harlequin in my sig), was again super sweet yet not nervy at all and he was an outdoor rabbit.
I think in all honesty, you need to be prepared that if you get a young bun, you have no way telling of how their personalities are going to turn out and a lot of is simply luck of the draw I'm afraid. Buns, by their nature are usually not all that 'cuddly' to be honest, and it's best if as owners we accept this before getting into ownership of a bun, because if they don't turn out cuddly, it's a 10-12 year commitment!
I'm well aware Autumns personality could change, she already has wee tantrums as it is.
Rescues are excellent because the people who will run the rescue will be able to tell you all about the personality of the rabbit, and being older and neutered, you are a bit more safe that the personality won't change. Neutering does help with hormone related behaviour which can make rabbits grumpy. Good Luck :wave:
