They don't get very big. The average hedgehog weighs around 9 - 19 ounces.
When a couple found a stray hedgehog in their garage in Somerset, UK, they thought he looked undernourished and felt sorry for him. So they started feeding him bowls of cat food.
Feeding regularly on a high protein diet, he quickly blossomed into a 4 1/2 pound hedgehog, unable to carry out his natural defense mechanism of rolling into a ball when in danger.

"We’ve had to house him in an otter box because a normal hedgehog one is far too small," said Pauline Kidner, of the rescue center which cares for 4,000 birds and animals a year. "His intake of cat food and cat biscuits has been reduced to 5 ounces a day so he’s gradually losing weight."
When he reaches around 2 pounds, he'll be released back into the wild.
