My bridge bunny Bicci was at least 9,she was a 4.5k cross lop. We had her 5 and half years she was nearly 3 years at the rspca and was a good adult when she was found and taken to the rspca. My other one tommy was at least 7 and another 4kilo +
My new ones:
My rew twinkle toese is about five and half weighs just over 2k and Ozzie is about 2 and weighs the same as twink. I was told the smaller the bunny the longer the life span expected. so hopefully we have many happy years to come with this new pair
