120 cats dumped into Hell CAN, and WILL, breed faster than they get killed. At least until you have 80 demons in the pit.

Sigged.

Not counting already mentioned cave-ins(automatic ice-based cave-in machine sending icicles down the 1x1(or 3x3, cave-in mechanics will drag the demons down anyway IIRC) shaft should do the work), you may try to exploit catsplosion in a way excluding instant destruction of the entire cat colony. Such as adding a syndrome with all available symptoms to their blood.

Shrike, 1) Fortifications prevent cave-ins, use buildings instead.
2) Cave-ins still instakill, regardless of their material.

RNG, just in case your fortress design did not account orbital bombardment, build the traps on additional wall layering. They-mess-design-up problem solved.
Problems with reusability should be solved by loading more than one cave-in charge and recharging your traps frequently. To do so, use hanging supports(example is in spoiler).

Retiring in a forest retreat actually does mean you've gone native. Your followers have nothing to do with it. It was that way in 40d, too.

A theoretical way to blind dwarves without taking eyes out of their sockets: mod dog blood to boil(don't forget to add [ENTERS_BLOOD] to it) and disable eyes on inhalation and contact, then drop a dog a few z-levels into a locked chamber with your combat engineers. They must be blind, at least for some time.

In "leaves" section, there are no Quarry bush leaves. Instead there are Rock Nuts.
The leaves themselves are both inedible and non-cookable now, rendering the quarry bushes useless.

A fire-themed possession occured right after I accidentally incinerated my pump operator in magma:
Tall crosses and a burning dwarf. Doesn't it remind you of something?

Experiment name:
Survival in cages

Experiment purpose:
How long will the dwarf survive in a cage, given the completely isolated self-sufficient complex designed and constructed specifically for the purpose of keeping them alive? How long will they remain sane? Are caged dwarves fed with prepared food or trapped vermin? Are caged dwarves' happiness affected by miasma and quality of food and water? Do the caged dwarves' wounds heal? What labor governs the "feed the dwarf" job?
Additional: Do the caged nobles mandate anything? Do the insane nobles in cages mandate anything? Are the insane nobles in cages replaced? Are the sane nobles in cages replaced? How long will the other group of caged dwarves survive outside that complex, depending on the unorganized haulers? Can a caged dwarf throw a tantrum? Will the caged dwarves be fed when the Tax Collector arrives?

Experiment size:
Small: A caging machine.
Medium to large: The life-sustainment complex.

Notes/other:
Using Dwarf Therapist when counting happiness is advised.
Preferable amount of test subjects in each group: four to ten.
Caging machine needs a cave-in generator and a cage trap. Complexity of life-sustainment complex is up to you.
