What is the Hedgehog Water Intake Calculator?
The Hedgehog Water Intake Calculator estimates how much water hedgehogs should drink daily based on weight and diet. Overfeeding is one of the most common and most preventable health problems in pets, while underfeeding a growing or active animal can slow development or sap energy.
A well-cared-for hedgehog usually lives somewhere between 4 and 6 years. As an insectivore, what a hedgehog needs from its diet changes across its life stages. African pygmy hedgehogs need a solid-floor enclosure kept at a steady 24-27C. Below that they may attempt hibernation, which is dangerous for them. They are solitary and must be housed alone. Health problems that show up most often in hedgehogs include wobbly hedgehog syndrome, attempted hibernation from cold, obesity, which is part of why tracking this over time pays off.

How does the Hedgehog Water Intake Calculator work?
The estimate starts from a resting-energy formula based on body weight, then adjusts for activity level, life stage and, where relevant, the specific nutritional profile of hedgehogs. Treat the result as a well-founded estimate. Every hedgehog is an individual, and your vet's judgement outranks any online tool.
Factors that matter
- Body weight: the single biggest driver of daily calorie needs
- Activity level: a sedentary indoor animal needs meaningfully less than an active or working one
- Life stage: since growing, pregnant or nursing animals need more energy per kilogram than a stable adult
- Spay/neuter status: which typically lowers metabolic needs somewhat
How do you use the Hedgehog Water Intake Calculator?
- Enter the body weight in whichever unit you use (lb, oz, kg)
- Answer "What do they eat?"
- Pick your climate right now (Cool, Temperate, Hot or humid)
- Pick your activity level (Low, Moderate, High)
- Press Calculate, then read the result alongside the sources listed below
One practical habit: revisit this every few months rather than checking once. Hedgehogs change as they age, and the right answer changes with them.

Before you rely on this
This calculation assumes a healthy adult hedgehog with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
