I had a cat who would run away from feet walking toward it.
This was an old, adopted rescue cat; a vet told me that the cat was missing teeth in front, and it looked like they had been knocked out.
We always thought the cat had been kicked in the face.
It took many years, but eventually Tillie got over that fear and no longer ran away when we walked toward him.
Bless our Karma’s heart... she is a rescue and will always watch her 6.
She is great with my chickens. My three girls are completely safe when she is on guard.
