Hedgehog-care education, not veterinary advice. Contact the actual veterinarian promptly about changed appetite, activity or other concerns; seek immediate veterinary help for breathing difficulty, collapse or mouth swelling. Do not wait for a note or app answer. No health clearance or safe waiting interval is provided.
Nocturnal describes a broad pattern
The fetched sources agree that four-toed hedgehogs are mainly active at night. RSPCA says their daytime rest should be left undisturbed. A broad pattern is not a promise that every night will look the same or that a particular change is harmless.
Quiet has more than one possible meaning
VCA Diseases describes illness signs as vague and nonspecific, including lack of appetite and lethargy. MSD notes that hedgehogs can hide illness. This website does not interpret stillness, a closed hide or a video as sleep, torpor, fear or disease.
Do not wait for a nightly deadline
There is no activity cutoff, minimum running distance or required number of minutes on a wheel here. A changed habit or concern belongs with the actual veterinarian. Do not postpone contact until a timer expires or until the animal performs a familiar behavior.
Leave the animal out of the form
Write only what is already known, without waking, touching, moving or testing the animal. Unknown is a valid entry. A note cannot establish that it is safe to wait, and ordinary-looking activity does not replace veterinary assessment.
