The most common species of pet hedgehog is the African pygmy hedgehog. An APH is a mix of the white-bellied/ four-toed hedgehog and the Algerian hedgehog.

Other type of pet hedgehogs are Egyptian long-eared hedgehog and  Indian long-eared hedgehog.

Keeping hedgehogs as pets became popular in the early 1980s.

Hedgehogs were originally classified as insectivores, but that order has since been abandoned and they are now in the order Erinaceidae.

They are not rodents and there are several factors that separate them from other creatures like rats, chipmunks and porcupines. The main factor for classifying rodents is their jaw and teeth.

Hedgehogs, unlike rodents, have canine teeth like a cat or human.

Pet hedgehogs still have a natural fear of predators (including humans) so they often ‘ball up’.

Handing a pygmy hedgehog a lot will help it learn to trust you and stop ‘balling up’.

Hedgehogs come in over 100 colours. Since domestication began, lots new colours of have been created this includes albino hedgehogs.

Pet hedgehogs prefer a warm climate (above 22 °C, 72 °F).

Pygmy hedgehogs do not naturally hibernate but if they get too cold they can try. This is very dangerous for them as it can kill them.

Hedgehogs in the wild eat a diet of mainly insects.

Pet Hedgehogs prefer a diet high in protein, low in fat. Owners usually give them good quality cat food with some treats like;


fruits & veg

cooked meats (unseasoned)


The Romans used to keep a relative of the Algerian hedgehog as pets in the 4th century BC! They used them for meat and quills. The quills they used were to help  train of other animals eg. to keeping a calf from suckling after it had been weaned. Even after the Romans stopped raising hedgehogs, their quills were used for card paper.

Pet hedgehogs are kept in enclosures so sometimes they are allowed in residences where dogs  and cats  are not allowed.

In the some parts of the USA & Canada it is illegal to own a pet hedgehog OR a license is needed to legally breed pygmy hedgehogs. This is because some hedgehog species can carry foot and mouth disease. These restrictions don’t exist in most European countries.

If hedgehogs don’t get enough exercise, obesity can be a big propbelm. You can see if a hedgehog is obease as it will have a double chin and fat drooping over it’s knees.

Due to their small size obesity is a very dangerous problem and hedgehogs require a fair amount of exercise.

Cages with wired floors are very dangerous for hedgehogs because they can get their little legs caught in the wire.
