Introducing 6 week old rats to 20 month old rats

[Charlize]

I'm new to the forum, and navigating the threads here. If this question has already been answered elsewhere, a link would be fabulous!

I've currently got two adorable girls that I rescued from the SPCA. Anova and Chi are going to be 2 on November 25. They are both spayed.

I will be getting two 6 week old girls in the middle of August.

Based on what I've read so far, there is a very gradual introduction process that needs to happen. Anova is my dominant female, so I'll have to keep an eye on her. I was wondering whether I needed to have the new girls isolated for disease sake for a while. This seems to be less clear on various websites.

Thanks!

Hi!
I would definitely quarantine the new rats and give them a couple more weeks to grow before trying any intros.
