How to tell your hedgehog's age?

[Worfhedge]

I just recently bought a hedgie, it's my first one. I was told he was 7 months old but I'm not 100 percent sure. Anyone know how I could tell his age? Or anything close?

There is no real way to determine a hedgehog's age. If they are babies we can guess a bit about their age if they go through age related quilling, however, once they are adults there is no real good method to it.

Love the picture.
