Animal clairvoyance

22 But God's anger was kindled because he went, and the angel of the Lord took his stand in the way as his adversary. Now he was riding on the donkey, and his two servants were with him. 23 And the donkey saw the angel of the Lord standing in the road, with a drawn sword in his hand. And the donkey turned aside out of the road and went into the field. And Balaam struck the donkey, to turn her into the road. 24 Then the angel of the Lord stood in a narrow path between the vineyards, with a wall on either side. 25 And when the donkey saw the angel of the Lord, she pushed against the wall and pressed Balaam's foot against the wall. So he struck her again. 26 Then the angel of the Lord went ahead and stood in a narrow place, where there was no way to turn either to the right or to the left. 27 When the donkey saw the angel of the Lord, she lay down under Balaam. And Balaam's anger was kindled, and he struck the donkey with his staff. 28 Then the Lord opened the mouth of the donkey, and she said to Balaam, “What have I done to you, that you have struck me these three times?” 29 And Balaam said to the donkey, “Because you have made a fool of me. I wish I had a sword in my hand, for then I would kill you.” 30 And the donkey said to Balaam, “Am I not your donkey, on which you have ridden all your life long to this day? Is it my habit to treat you this way?” And he said, “No.”31 Then the Lord opened the eyes of Balaam, and he saw the angel of the Lord standing in the way, with his drawn sword in his hand. And he bowed down and fell on his face. 32 And the angel of the Lord said to him, “Why have you struck your donkey these three times? Behold, I have come out to oppose you because your way is perverse[b] before me. 33 The donkey saw me and turned aside before me these three times. If she had not turned aside from me, surely just now I would have killed you and let her live.” 34 Then Balaam said to the angel of the Lord, “I have sinned, for I did not know that you stood in the road against me. Now therefore, if it is evil in your sight, I will turn back” (Num 22:22-34).

Many unbelievers regard that as one of the most fabulous stories in the Bible. They single out the donkey's supernatural ability to speak.

However, the account also credits the donkey with the ability to perceive the angel, which was invisible to Balaam. Are there other examples of animal clairvoyance? 

At one time, Michael Sudduth resided in a haunted house in Windsor Connecticut. At the time he and his wife didn't know they were buying a haunted house. It was a historic colonial home. After living there they discovered that it was haunted. And subsequently, they found out that the previous owners had the same experience. (I think Michael's experience in the haunted house, on top of his youthful dabblings with the Ouija board, is one of the things that pushed him off the deep end.) Among other things, he recounts the following:

The family dog (a golden retriever named Abbey) also seemed to sense something in the house. Early on she had some very strong reactions to something we could not see, much like she would if a stranger come to the house. She would go a particular spot in the house and look up and bark at something she had focused her eyes on. Sometimes she would stare down the stairs from the top of the stairs, as though she were looking at something in the foyer downstairs.
This happened in several places in the house, sometimes when we heard things and some- times when we had not. On one occasion Abbey became extremely aggressive, almost violent. She was really spooked by something. On at least two occasions, while I was teaching night classes, Jill had locked herself in the master bedroom with Abbey for fear that someone had broken into the house. Over time while Abbey continued to act as though she sensed something, she was not as disturbed, exactly as she behaved with guests with which she had become acquainted.

You might dismiss this as subjective, but Sudduth also recounts objective phenomena which collaborate the dog's clairvoyance. For instance:

One day after we had been in the house for a few months, Jill and I were having an argument about the house. At one point, Jill said: "We should just sell this damn house andleave!" Immediately a short umbrella we had hanging on the coat rack by the backdoor flew off the peg and landed about six feet or so from the door. The peg did not break. There was no door or window open. And the umbrella was still rolled up. This umbrella just launched itself across the room. We were speechless.

Out of curiosity, I wrote Dr. David Hufford. He's a college prof. at at the Penn State College of Medicine (Hershey), where he has appointments in Medical Humanities, Behavioral Science, and Family and Community Medicine. He's a world authority on old-hag syndrome, based on extensive original research (e.g. interviews, case studies) that he's conducted over the years. 

In your research, have you run across credible reports that animals, like pet dogs and cats, can perceive the unseen presence of "spirits." Sense the presence of personal entities which are invisible to human observers?

To which Dr. Hufford responded:

I have reports I consider credible. Most do not involve "hagging," but some do. I am convinced that this happens.

So there is corroborative evidence for animal clairvoyance, of the kind exhibited by Balaam's donkey. 

I should add that Rupert Sheldrake has done extensive research on animal telepathy:
