Any idea how to best keep feral cats from devastating a bird's nest about 20 ft. up a tree (besides relocating them). Just chased one away that was starting up towards the nest that has a pair of mourning doves. Would putting a cage of chicken wire around the trunk)5-6 ft high keep the bird's nest safe?

Well, that was fast. Looks like Mr. and Mrs. Mourning Dove decided to build their nest elsewhere! Probably a smart move!

If it's loosely fitting, possibly — as long as their claws can't grip the bark. Or maybe something more like a a squirrel baffle out of chicken wire, sort of umbrella shaped.
