Today, we had a visitor

One sunny day earlier this summer I was chatting with a neighbour in her front garden when we were disturbed by the sound of cats getting ready to fight.  I walked along the road till I found the site of the battle. A large black and white cat was facing a small black cat and looked ready to establish that this was her territory.  I have often seen the small black cat, but the larger cat was new to me, and it looked like she would win if she started a fight.  So I intervened from a distance and the black cat was able to run for cover while the larger cat was distracted.
Now, when I see the small cat she stops and miaows and has taken to visiting our back garden.  Today, while I was working in the kitchen I spotted her sitting patiently close to the large bay tree where there is plenty of cover for mice and birds.  I think she was probably hoping to catch a meal, but her owners have placed a bell on her collar so I don't know how successful she is at hunting.  She certainly doesn't look hungry.

She seems to have a few grey hairs

                                                                           

Does she remind you of anyone?
