I have a bunch of extra cage panels from cages similar to this

left over from joining two cages together.
The panels are 30" by 18", and they look really nice, but they don't have doors.
So I got these kind of pliers

and was able to cut door openings, and cut pieces into the right size for doors. Hooray!

The cuts are pretty close, but not exactly perfect. There's still a really sharp edge each place I cut a wire.
I'll be building 6 cages, so I don't want to file each bump by hand.
