I recall reading that
pointing is something that only a few animals, including us, do and understand.
If I get my cats' attention and point at something, they're more interested in the tip of my finger than the direction I'm pointing at.
Now, my cats will occasionally meow to get my attention and then walk over to where the problem is - an empty food dish, an empty water bowl, the bed that they expect us to be in because hello, it's bedtime according to my internal cat-clock - but they never engage in pointing behavior.
Anyway, time to cite some stuff, instead of dropping anecdotes into a bucket:

> A study by researchers from the University St Andrews has found that elephants are the only wild animals that can understand human pointing without being trained.
> Pointing in humans is a behaviour that develops at a very early age -- usually before a child reaches 12 months – as it is an immediate way of controlling the attention of others. "Most other animals do not point, nor do they understand pointing when others do it," says Professor Richard Byrne, one of the authors of the study. "Even our closest relatives, the great apes, typically fail to understand pointing when it's done for them by human carers; in contrast, the domestic dog, adapted to working with humans over many thousands of years and sometimes selectively bred to follow pointing, is able to follow human pointing -- a skill the dogs probably learn from repeated, one-to-one interactions with their owners."

> If the distance between the tip of the indexfinger and the object was greater than 50 cm, subjects per-formed poorly in contrast to trials where the pointing fingeralmost touched the baited box. We should also note that insome trials/experiments the pointers also turned their headand looked in the same direction thereby enhancing thecommunicative effect of the gesture but even so the differ-ence did not disappear. Even after training, chimpanzees in Povinellietal’s (1997) experiment were just able to master the task.
