Right, I'm not an electrician and I don't claim to be.

I'm not a licensed electrician, either, but I've had 3 years of electrical school and 2 years of voice/data/video tech school and 2 years of plumbing school and 2 years of HVAC school.

At one point I owned a lot of rental property.

I've mostly only actually done the renting.

I never experienced rodents chewing through metal electrical boxes.
Not saying it can't happen but my guess is it's very rare.

In large urban areas, it happens. Depends upon if there is a particularly bad rat infestation at that time or not. You come to the job site the next day and sometimes see the damage. Metal is always your best bet on new work. I'd choose it for remodeling, too.
