My guinea pigs liked my fingers... and anything else they got to eat... The younger one took a bite from his older brother's ear once... And then called him "Dog-eared Tom" all his life. Those were hard times for a guinea pig...
I've never had Guniea Pigs..i had two fishes.once...but one hung it self...from the tree..or it got stuck and died.. I wonder if they ever hated me, probably did.. I wasn't the best owner...
but then again how do you show love to a fish????
