I'm looking after my little brother's Guinea Pigs whilst he's on holiday. I'm trying to work out why anyone would choose to keep them. They look like a rather elderly mop head (though, be warned, don't use them as one: they take ages to dry out and the squealing if you try and wring them out is pitiful) and are frightened of noise, movement, noise and movement and probably a lack of noise and movement. One of the four has to be kept apart from the others because it's male, but too young to be neutered and is likely to screw the others to death if given the chance. Apparently, they can die of a heart attack if handled too roughly.

You could stroke one if you don't mind stroking a quivering ball of fur I guess...
