My small friend seems utterly indifferent to low noises (fireworks, thunderstorms, explosions in movies, vacuums...), but this may be because he lives with a bass player so hears a lot at lower frequencies. He's much more inclined to bristle up at higher frequencies -- he hates sudden click-noises, and hyperventilated when first hearing a tin whistle.

I'd say wait & see. Different hedgies will be accustomed to different noises depending on how boisterous their living environment is, I suspect.

 

Alright, thanks... I'll keep an eye on him today during the storm.

 

I haven't had any problems with storms. I have music on all the time so they don't really seem to be startled by outside noise

 

On the 4th of July I was more startled by Pig's random sleep-squeaks and snores than I was the fireworks! That little hog sleeps like a rock.

There's actually a big thunder & lightening storm happening right now and the only reason he's awake is that it's 1am....aaaand the power just went out. And he's asleep again. Guess I should go to bed, too.
