I have had my pig since July. He is the sweetist thing. He eats food out of my hand and always runs to me when Im by his cage. But any time I try to pet him or pick him up he runs away. I have to corner him and try to grab him any time I have to clean his cage or plan to give him lap time. I understand that they are pray animals and are used to fleeing. Some of you have had guinea pigs all your life, do most of your guinea pigs lighten up after a while, or are they always that way (or does it vary depending on the pig)?
