Going to adopt some (spayed) girls after having boys, what should I know?

I’ve decided I’m going to keep Toffee. There was a really bad rat hoarding situation in Ohio, and a rescue from Indiana rescued a lot of them. They’re spay/neutering everyone after their severe health issues have been dealt with. I’ve already put in an application for two girls to be friends with Toffee.

I know girls usually like to play more than the boys do. I know girls love having a wheel and I’m planning on getting them a wheel. I also know they love to learn tricks, I plan on teaching them so they can focus on that instead of the past neglect.

Is there anything else I should know? I do know how to do introductions! But anything when it comes to caring for girls, I would love any advice.

After I get these girls and everyone passes away, I’m definitely taking a break. I miss Dusty so much. He meant so much to me and was doing great the night before he died. But I refuse to let Toffee be alone after the other senior dies. I do know that is animal abuse.
