It comes in different gauges. Different stores offer varying to no variety of gauges, but you can get it.
There are very few things that are literally going to tear through chain link fencing, and only slightly more that will get through hardware cloth. I think the major premise behind hardware cloth is to deter critters from reach through fences with large holes and grabbing chickens (which they will then proceed to tear through in a very unsavory manner). In our run, the primary fencing is 14 gauge 2"x4" welded wire. Hardware cloth is installed inside that to a height of 4 feet.
