Oh Raglet, please let us know as soon as she turns up. I will worry!
I really hope she is okay. Could she be getting fed elsewhere? We have two cats of our own and one stray who we feed. Although she sleeps every night in our Garage she wanders an enormous distance, and I am sure others feed her too. Maybe a check up with the vet would be a good idea. Is she old enough to be getting a little silly?
