Oh No! Poor Mimi! And poor you and Helen too!
I'm so glad that you two got there in time to rescue her.
Don't be surprised is she is afraid to go outside for a while.
A few years ago Samantha got in a fight with a big tomcat from up the road right on our front porch.
She was afraid to go outside for months after that.
I would spoil Mimi and keep her in as much as possible and only let her out when someone is home to keep an eye on her.
Hugs to you Logan, it must have been so scary.
I'm happy to hear that sweet Mimi is ok.
