This is really gross, and not serious, but maybe they were hungry.......? Amos and Wolfgang, I am not sure we are discussing "psychic" phenomena here, just that other animals do know things humans don't......how, we don't know, but we do know that they have sensory abilities beyond or different from ours.

I've often wished I had whiskers to tell me things that cats and dogs know, or their acute sense of hearing since mine is so depleted. Don't know if I want the sense of smell, tho........or sonar like the ceteacans (did I spell that right?) A tail to switch to indicate emotion would be nice too, sometimes.
