Logan, I meant to reply to this thread earlier, how is Mimi doing today?
I would keep her inside where you can keep an eye on her and make her as comfortable as possible, it sounds like she is happy to cuddle up with Helen.
Samantha gets the royal treatment here, sleeping where she wants, when she wants. She is usually right by my side or under my feet.
I hope Mimi is eating more now that Helen is back. My Samantha has never had a problem with her appetite, she is on diet food and she always cleans her plate.
I would just say enjoy every minute you have with Mimi and give her some loving every chance you get. Sending hugs to you and sweet Mimi.
