I have had 6 guinea pigs over the years. My last one died a couple years ago. His name was Tiko and he was a Peruvian with hair that measured 8 inches long from the part down his back! I had never had a Peruvian before and he was very smart. He would "allow" me to take him out of his cage, but he insisted on putting himself back in! If I needed him to go back in I could either chase him around the living room, or tell him I needed him to go home and step away. Then he would calmly walk to the cage door and step in! He was like a little dustmop with feet. He would follow me to the kitchen squeaking away when I got out the vegetables. He loved tomatoes and romaine lettuce. My elderly mother lives with me now and she has 2 old cats, one of whom has adopted me as his own, and he would be very jealous if I brought in a new "baby". So for now I have to hear about other people's piggies and pet them at the pet stores. Someday I'll have piggies again.
