The cat that is eating the bread, was she or he a stray?
I adopted a stray female up in New Hampshire, named her MiaMia and brought her home.
I have never seen anything like it. She didn't know what cat food was, didn't know what chicken was, didn't know what hamburger was, but you could not leave a loaf of bread within 500 miles of her, but she would be in it and at it.
When we ordered delivery pizza, we couldn't get her to eat the cheese, she ate the crust. Only the crust.
We finally figured out that she had been a stray so long that the only thing she could find to eat was bread. It took her a year and a half to realize that the big bag of stuff that made noise was NOT the vacuum cleaner, it was the bag of cat food.
