noisy bunny ?

have you ever heard a bunny sneezing ? or squeaking ? oh yes, that's true..I'm not kidding. My 5- month old female is a very noisy bunny.
I'd never heard a sound of a rabbit before ( in fact I'm sure most of you also think that a rabbit doesn't sound at all ) until I had Dolfi. I bought her when she was about 2 months old from a petshop. She is a Lion head bunny ( some kind like a crossbreed of English Angora ). Her thick brown smooth hair and white spot on her nose soon made me fall in love with her. It's not long after I brought her home that I discover that she is a noisy bunny. She squeaks when I give her a small treat (almond biscuits), showing that she enjoys it very much. She also often does something like sneezing but without having a cold. And the most interesting part is now her soul mate, Molly, a 6-month old female Angora, learns to make sound like her although very rarely
