t. I don't even think that my design has a valid path between my spiders and my bait, all doors are forbidden and the mongoose is pitted from a level up. - If a wild wolf doesn't work for you try pitting a goblin as a bait.
I can verify that now. GCS reverted back to wild and started to attack a chained tame giant raven, through fortifications with no paths to the Raven.
Dog on the other side is in peace, though he can be pathed to.
I left the corridor to the Raven open to dwarves, with no traps on it, so far they've been getting the silk from there,
and not getting blown through the fortifications though there's traps on the other side and the GCS is spitting quite a lot at them.
It seems it may be quite a rare stumble, if one gets pulled by the web through fortifications to a web covered cage traps.
But they don't seem to be pushed by webbing to similarly web covered cage traps.
Anyway, hoping to get some FBs caged next, or failing that, HFS caged.
I would like more GCS's though... Both trained and wild.
As for worrying about cats killing GCS, I think I once did have a hard-ass cat that killed one.
He had earned a name, or did by doing so. Hunted all the spiders extinct... nowadays I don't let the cats out until I have caged a GCS.
...And seems that it was a bad idea to allow dwarves to the adjacent 1-fort-away -corridor to collect the silk, as one just shot the spiders' brains out..
2 forts away(with spiderannoyer-pet corridor) seems to be safe, thus far.
...
And I must add, that I don't recommend any traps on the 1-fort-away adjacent corridor, next to GCS, as they seem to only cause trouble if any dwarf
comes close to them or you need to switch the animals the GCS is attacking. Again, beware hunters and military doing the job.
