New guinea pig owner and have had Cleo for around a month and half now and up until around a week and a half ago she was fine with being picked up having lap time and anything else and never complained. Now she hates being picked up with a passion and will not tolerate being out of her cage outside of floor time. She continues scrambles down my arms nipping at me as she goes and constantly letting out small squeaks till today when she bit me to the point to draw blood. Her sister pippa on the other hand hates to be removed from the cage but once out she's happy as can be and will take a nap while laying with me she just hates actually being lifted and has never even tried to nibble.
