📏Growth & Size Facts
The Curl Test
A healthy hedgehog can curl into a tight ball. If they cannot fully curl, they are likely obese.
Fast Growth
Hedgehogs reach adult size by 6 months. Rapid weight gain after that is usually fat, not growth.
Nightly Weigh-ins
Weigh weekly on a kitchen scale. Sudden weight loss may indicate illness.
Exercise Wheel
A 12+ inch wheel is essential. Hedgehogs can run several miles per night.
