Cat up a tree.

Ginny has the strangest behaviour when chancing upon a cat encounter.  At the allotment today as we walked along the tracks she spied a cat and they both went into a "Mexican stand off".  I shortened her extendible lead in case she charged at it which is exactly what she appeared to want to do but when cat decided to make a swift bolt she let out a terrible blood curdling cry as if she had been attacked which she had not.  This is exactly was she did on a previous occasion (different cat).  She is at the same time both brave and absolutely terrified.  The cry was so scary that the cat bolted up a tree - today's blip.  We walked on and when I looked back the cat had safely climbed down thankfully and was walking off in the opposite direction.
