unless you're planning to cut a wider roll of HC lengthwise, which is a chore - but an angle grinder makes that easier if you have access to one.
These are inexpensive as tools go and make cutting both hardware cloth and metal roofing a breeze -- and I'm a short woman with arthritis in my wrists.

(Don't get these, because they take a kerf and would salt your yard with bits of metal).
I'd either get some pressure-treated 2x4s to install on the bottom, or elevate it on something like cinder block cap stones before doing the skirt.
Which would have the added benefit of keeping the run litter from spilling through the wire.
