I currently have a 4 year old male and a 5 year old female. They get along well. I'm getting a pair of sibling kittens soon and got the advice that getting 2 boys would be best for peaceful co-existence, however my family has fallen in love with one of the girls in the litter. We have a big house, have watched all the Jackson Galaxy videos and thecatesite articles on introducing cats, and will do our best with all those tips... but how common is it for 3 boys and a girl to get along better than 2 girls and 2 boys. I've been told all the kittens have good personalities... but they're only 6 weeks old and I don't have to make a final decision until they're 10 or 12 weeks so I'm imagining I will know more about their personalities... but if they seem to be similar temperament wise I'm wondering how much I should take into consideration the advice to get two boys? Thank you. .
