Well there's different degrees of humane. I know a company in ND
that makes fence insulators quit making RED insulators because
Humming Birds would be attracted to the red color, get
zapped and die. Small animals might be at risk too because
most electric fence "chargers" are made to control larger
animals and "burn" weeds. I would imagine that the AC
continuous types would be the worst to use if small animals
can get zapped.

I've been using ~#15 gauge aluminum wire for open wire
transmission line for many years. One of my spans that feeds
my 160 transmit vertical is well over 200 feet long and has
survived several ice storms.
FWIW, the "trick" to installing it is to:
1. *Never* allow it to kink. It's guaranteed to break if you do!! :))
2. When splicing use a "Western Union" splice. I use 6 inches
of wire on each side of the splice.
3. Use connectors rated for AL-CU when connecting to copper wires.
