wire

So I thought that my guinea pigs couldn't get to the charger cable of my phone but they did, they bit a bit of wire out. So far they seem normal and none of them seem lethargic. None of them were electrocuted. Do you all think they will be okay?

hi all I have my piggies in an outdoor hutch currently but hubbie has agreed they can move inside for the winter. Hurrah! I am going to make a wooden frame and then line it with wire mesh. My question is galvanised or pvc coated? I assume 13mm gap rather than 25mm is best? I do not want to...
