Mine don't care to be honest. I have them in a shed and I just shut them up early to hopefully make them feel more secure. I dunno what my young guinea pigs will make of it, I will give them a huge ammount of bedding so they can hide in it if they want to.
I have a dog and cat who are terrified tho

damn fireworks!
