This cat was looking for a fight.
I was walking peacefully with my dog. I was between my dog and the cat, so my dog is hiding behind me and using me as his shield.
In these situations, I always make noises so the cat knows that we are coming and usually either the cat moves away or stays circumspect. Not this cat, s/he decided that s/he was going to attack. I knew that. I quickly made my photo and kept on walking.
S/he started to launch, I quickly turned against the cat. I made big noises and big moves with my arms and then the cat decided that we were not worth the trouble s/he would get into. Then s/he disappeared who knows where.
