Two laws of physiscs that are irrefutable: A cat always lands on its feet, and a buttered bread always lands on the buttered side. Ergo if you attach a buttered bread to a cat's back and connect the cat to a generator, you can create infinite energy.


The perpetual buttercat mechanism gives your setup the following stats in addition to its raw and mystic power:

Efficiency (bait usage)

The perpetual buttercat is an antiburner that counters two additional bottles of bait for each hunt.

You can combine the perpetual buttercat with other burners or anti-burners to adjust the number of bottles you will use each hunt.

Burner use and strategy

Dealing with the burner aspect of the perpetual buttercat is a perfect example of the kinds of choices and trade-offs you must make throughout Virtual Scotland.

There is no correct answer — there is simply the choice that benefits your current goals the most (or the choice that minimizes the amount of pain you feel watching bait disappear). It's all a matter of taste and your current goals.

Many people prefer to use cheaper bait with the perpetual buttercat. They tend to see burner components as an occasional necessary evil.

Others will use Nessy's Golden Reserve or mocktails with the perpetual buttercat in their setup, because they are trying to capture a ghost that requires more raw power, more mystic power, or more something to catch than is otherwise available. Again, this is purely a matter of taste.

Only you know what is most important to you in Ghost Trappers right now, and that is probably the most important factor to consider to help you determine the best strategy for your own use of the perpetual buttercat.

Additional information


The perpetual buttercat mechanism can be assembled in the Q-Section outpost of S.C.O.T.C.H. HQ in all normal, non-raiding locations (including all AV locations, and all spider den and trapdoor locations) once you have acquired the necessary blueprints (see below for details).


The perpetual buttercat is an outworldly trap mechanism.

Mechanism blueprints

You must collect the following mechanism blueprints/schematics to be able to assemble the perpetual buttercat mechanism in the Q-Section at S.C.O.T.C.H. HQ:

The perpetual buttercat mechanism can be modified by negotiating a contract with one of the contracts listed below.

All of these contracts are designed specifically to work with outworldly mechanisms.

In addition to these contracts, you can also use any of the contracts that are designated as magic circle contracts. Those contracts can be used with all types of trap mechanisms.

How to decide which contract you want to use

There are a lot of different contracts you can use. Each contract has a different combination of stats. Use the contracts compared page to see how all the contracts stack up in terms of specific stats.

Each stat does one specific thing to your setup ... to play the game successfully, you need to figure out which set of contract stats will help you meet your goals.

That means ... you have to figure out which stats are most important !


Stats page

The stats page gives you a quick definition for every stat and links you to the stat's own page.

Each stat's page lists all the equipment that can add that particular stat to your setup.

The contracts compared page

So once you know what stats are most important to you at the current time, check out the contracts compared page. It allows you to sort on its columns—so you can sort each stat from low to high, and then from high to low. You can see which contract that you own will be most helpful to you. You can also see what other contracts might help.


Your mechanism and contract stats will be combined with all the stats from other kinds of equipment in your setup.


  • 1 April 2017: The Perpetual buttercat mechanism first appeared, in outline form, in the office at S.C.O.T.C.H. HQ.
  • 24 April 2017: The first blueprints for the perpetual buttercat mechanism were dropped as loot.
  • 13 June 2018: The perpetual buttercat mechanism gained the happymaker stat.
