do not respond to pointing, either. Dogs and cats do, but chimps do not.

narrated by Alan Alda which showed chimps being tested on how they act in various situations. When they failed to respond to pointing, dogs were shown to respond. Alda mentioned that cats also respond to pointing.

The cat that I had at the time would always respond when I pointed to something on the floor with my foot, but rarely when I pointed with my finger. My current cat often, but not always responds to finger pointing. But, like my previous cat, she does respond every time to pointing with my foot.
