@ToonLink Yes! But you see the door/windows behind her on the photo, for a long time, it was the maximum distance she could get inside while Charlie was jumping on all sofas, desk, and visited every "under of furnitures" (good little duster).
This morning, she tried to enter a little more, just a little circle of 2m or 3. And we were excited to see that!

With her, there is no big 'breakthrough" and it's very step by step, everyday, a little difference.
