I started with a trio back in 1998 and had a great time with them and built them a large enclosure, they loved it. Just make sure whatever cage you get for them is something you can wash down well with soap and water because the male will spray his scent around and it can get strong. They have come along way on pelleted foods for them. Which I think are great products. Good luck and wait until the baby comes out they are a lot of fun. Just think next time she will have 2 babies.
