We had three guineas, when I was little, one after the other, not at the same time. Ginny the first one, was just a guinea pig. Chocca the second (she was chocolate coloured) was very smart indeed. She learned the sound of my Dad's footsteps as he walked home from the shops, and whistled to him, knowing that when he got in, he'd come out and feed her, or put her run out on the lawn. Over winter, we brought her inside, as the shed was very damp, and she learned the daily routine of the house, right up to the fact that Mum would bring her a last lettuce leaf or carrot last thing at night, and she (Chocca, not Mum) learned to listen for the kitchen light switch clicking, and started whistling then. She (Chocca again, not Mum), also learned to do all sorts of other stuff. She'd run laps of the room, or jump up onto a box or something, and sit there looking regal. Very sociable and vocal, and adored grapes.
When she died, at a good age, we got Ashley (long haired grey) and she was a bimbo and thick as two short planks. Her eyes were too close together to allow for any brain between. She had all the same stimulus offered, but resolutely just sat there. We'd often find her looking hungry, sitting on her dinner.
