I have three tortie girls, the eldest, Tiffany is about 18 months, Bellinda is just about 6 months and Jessica is closer to 5 months. We lost Peppina at the beginning of July she was ages with Tiff, introducing Bell wasn't too bad but Tiff was very unhappy about Jess coming along. We got them all around 8-10 weeks old have had them all together for about 3 months. They are great together.
There was a time we thought it just wasn't going to work but it has. They are all indoor cats who seem happy enough to chase each other
