you can tame spiders (normal only, not cave) with beef. (Make sure you tame only one, because it's really buggy for now)
Also, they are become unkillable when you tame them, and the collar was added using resoursepack.
I created this pack because the original mod's author has not updated it for newer Minecraft versions. (https://www.curseforge.com/minecraft/mc-mods/tameable-spiders)
