It is my understanding that there are certain character traits more likely in certain breeds of rabbits-but obviously that’s not a given. Really, even with dogs or cats, or an animal more likely to be bred for character-those particular animals don’t always have those given traits. I have a mini rex who weighed 2.3 lbs. at her last vet apt. and she is very friendly, curious, active, and loves to be petted-not so much picked up. I have a holland lop who will likely end up under 4 lbs. and she is sweet, but more nervous, and has a quieter personality. I think they are both good breeds and you can look them up on the internet. I think it’s great to get rabbits from shelters but not everyone has a rabbit shelter nearby and regardless, someone brought that rabbit into the world-whether it comes from a shelter, a breeder, a pet store, or a friend, and if you can love it, take care of it, and give it a good home I think that’s great! Good luck
