I try to give new rat owners the benefit of the doubt. I realize that some of them didn't know what they were getting into when they adopted their first rat. And I try to help them to do better for their best furry friends within their means. The world is not fair to rats, it isn't fair to wild rats and it is unfair to domestic rats. For the most part, better is always possible and good is usually achievable. Optimal is best, but were a long way away from a perfect world.
We currently have a two rat limit, which means we replace one rat when one rat dies. Due to no fault of our own our rats are currently about a year apart in age. So right now, Misty is almost one-year-old while Cloud is almost 2. Misty is energetic and playful and Cloud pretty much sleeps all the time. Cloud is Misty's great aunt and they really do get along very well and they clearly love each other. Misty steals stuff from all around the house and Cloud builds elaborate rats nests out of it. But as far as really playing together goes, I don't think that's really ever happened. Naturally, my daughter and I try to fill in as best as we can when it comes to playing with Misty. Hopefully, Cloud isn't in any hurry to weeble over the rainbow bridge, but that means Misty will be older by that time and the cycle is likely to repeat itself again.
Letting our older rat live out it's life alone or adopting another old rat to keep it company isn't an option for us either.
I don't think it's a bad situation, in fact, as all of our rats have been, at one time or another, likely to become snake food, I think they've done pretty well in our home. But like I said, good is better than bad and optimal can be very elusive.
