Guinea pig behavior education, not veterinary advice. Illness or eating concerns need the real veterinary service. Difficulty breathing is an emergency; suspected seizures need contact straight away. Do not wait for a note or app response. No health clearance or safe waiting time is provided.
Hiding has an ordinary place
MSD lists hiding among normal guinea pig behaviors. RSPCA describes constant access to safe hiding places and the ability to retreat from frightening things. A hiding place is not a reward that has to be earned by jumping or interacting with a person.
One event does not answer every question
A retreat after a sound and an animal hiding much more than usual are different descriptions. RSPCA includes hiding most of the time among possible signs of stress or fear and recommends advice for ongoing concerns. This page cannot determine the cause from a single field.
Leave experiments out of the frame
Do not block a shelter, draw an animal out or introduce a noise to see what happens. No hiding-time threshold, enclosure certification or pairing recommendation is provided here. For practical welfare questions, use the cited guidance and a real qualified service.
Keep a concern visible
A known change can be named without diagnosing fear, pain or boredom. If eating, breathing, movement or general health is concerning, veterinary contact takes priority over trying to obtain a clearer view.
