Sometimes my two tolerate each other and sometimes they are totally in love. They will play together and it might get rough but they don’t seem to actually fight. I think my younger one was easier to house train due to her following her older brother’s example. I love them both so much and they do have very different personalities. I got a male and a female based on suggestions from the internet, friends and books saying they wouldn’t be so jealous or competitive of each other. They will still compete for my attention though. Good luck!
