Leo

Shortly after this Leo stepped up to project his "sister" Coco! Another cat came into the garden and Leo who is usually laid back and chilled was very vocal and chased the intruder. Poor Coco was quite frightened and Leo was spooked too.  
It turns out Coco had been in a. big fight with the other cat sometime ago and was badly shaken.  
However, the poor mouse which I found laid out in the garden didn't have a " brother" to protect it!
The human teenagers were in an argumentative mood also.
