This article is about an older version of DF.
D4Dwarf.png This article or section has been rated D for Dwarf. It may include witty humour, not-so-witty humour, bad humour, in-jokes, pop culture references, and references to the Bay12 forums. Don't believe everything you read, and if you miss some of the references, don't worry. It was inevitable.


Your cat kills a vermin.
It reaches down to pick it up.
It realizes it has no hands, cries out "My hands! My beautiful hands! Someone has chopped off my beautiful han... wait, I'm a cat, I don't have hands. Right," and then continues on with its business.

This error announcement is actually caused by an old bug in the system which was reintroduced in 40d. When a pet cat kills a vermin, it picks it up with its mouth and carries it to its owner, to bask in the display of gratitude that every cat owner shows upon being gifted small dead animals.

Once it gets to its owner, it realizes that it needs to get rid of the vermin and decides that the best way to do this is to haul it to a refuse stockpile. However, the cat's mouth does not possess the [GRASP] tag, so it generates this error message and drops the vermin on the ground (which it was supposed to do in the first place).

Fixing the bug

As your cat and vermin population expands this message becomes more and more common, but it is easy enough to fix by modding (the exact steps are explained below). You don't even have to generate a new world.

Step One

Open raw/objects/body_default.txt and add a new entry:

[BODY:CAT_MOUTH]
[BP:CAT_MOUTH:mouth][CONTYPE:HEAD][MOUTH][SMALL][EMBEDDED][APERTURE][GRASP]

This creates a new body part in your dwarf universe. Specifically, a mouth which can pick things up. Now we need to attach this body part to the cat!

Step Two

So open raw/objects/creature_domestic.txt and edit the cat to:

[CREATURE:CAT]
       [NAME:cat:cats:cat]
       [TILE:'c'][COLOR:0:0:1]
       [VERMINHUNTER]
       [PETVALUE:20]
       [CARNIVORE][NATURAL][PET]
       [LARGE_ROAMING]
       [COMMON_DOMESTIC][BENIGN]
       [PREFSTRING:aloofness]
       [BODY:QUADRUPED:TAIL:2EYES:2EARS:NOSE:2LUNGS:HEART:GUTS:ORGANS:THROAT:NECK:SPINE:BRAIN:CAT_MOUTH]
       [BODYGLOSS:PAW]
       [SIZE:3]
       [MAXAGE:10:20]
       [ATTACK:MAIN:BYTYPE:MOUTH:bite:bites:1:6:GORE][ATTACKFLAG_CANLATCH]
       [CHILD:1][CHILDNAME:kitten:kittens]
       [FAT:1]
       [DIURNAL]
       [STANDARD_FLESH]
       [HOMEOTHERM:10070]
       [LAYERING:100]
       [SWIMS_INNATE][SWIM_SPEED:2500]
       [MUNDANE]

And you're done.

Noted Error: Once a cat adopts a dwarf, this no longer works


Note that you don't have to edit the [ATTACK] line, even though it contains a MOUTH too. This is because the "mouth" in this case is referring to the [MOUTH] body part token, not the body part itself (you'll note that our CAT_MOUTH has this mouth tag, too).
