She never ever stays out after dark.
She went out last night for a wee and I went to bed. DH left the window open for her to come and go as usual except she wasn't there when we got up this morning.
No sign all day, we've driven around half expecting to find the very worse and DH is out looking for her in the neighbourhood now.
When would you start to really worry ?
I just cannot bear the idea of her in pain somewhere :-(
