I'm making a world where I want domesticated Mimics to be a thing.

These Mimics are pretty similar to the original concept of D&D Mimics: shapeshifters that imitate objects, and hunt by imitating something desirable to their prey, then attacking when the prey comes close using a sticky secretion and a bludgeoning pseudopod.

The questions I have are as follows:

1. Why would a creature with this kind of lifestyle be trainable, let alone domesticatable?


2. How might one go about domesticating and training them?

Animals that humans have domesticated tend to have similar characteristics: social, active, and preferably herbivorous (with a few exceptions). Mimics are none of these.

I want them to be roughly similar to dogs in intelligence: not civilized creatures, but smart enough to learn and sociable enough to train for various diverse purposes (the most obvious being as house guards, but can also make good pets, can be used by hunters as decoys, and can even help the disabled using the versatility a tentacled shapeshifter has to offer). As with dogs, they come in various different breeds that vary in size and disposition.

The exact details of their evolutionary progress aren't important (they can be presumed to have evolved from an already existing class of amorphous muscular blobs) but they are a natural creature that evolved in a natural environment, without magic or human involvement ("wild" Mimics usually imitate plants or dead animals to lure their prey). As such, their intelligence and disposition should make sense for a creature with their lifestyle to have.

Additional details about these Mimics:

Mimics are obligate carnivores. Like snakes and crocodiles, they prefer large single meals over regular small ones, at least in the wild.

While they can change their topography, color, and texture, and are capable of "locking" their muscles into place to remain stationary for long periods of time without expending excess energy, they are basically muscular blobs and can't really maintain a convincing shape while in motion (though they are capable of "jiggling" a part of their body to attract prey, and can form basic shapes like tentacles). They also can't change their mass, though some cleverer ones can change their apparent volume by expanding hollow spaces inside their bodies.

They are not good at moving quickly (the fastest they run is about the speed of a brisk human walk, and they don't like to do this often) but they can lash out with a pseudopod extremely fast, and they can climb walls using a combination of shapeshifting and their sticky glue. House Mimics can be trained not to "slime" but this is difficult.

Wild Mimics rarely prey on humans (not enough opportunity for the risk, and not enough overlap between the items humans go for and those that more common prey go for). Most "chest Mimics" are domesticated Mimics who have been specifically trained to guard a house by imitating an object that a thief is likely to go for. Some notorious Mimics have been known to target humans though; as with other "man-eating" animals they are usually hunted down and killed.

They can see using any part of their body, but their "eyes" must be dark and smooth for them to see effectively. This makes it difficult for them to disguise themselves perfectly and see at the same time.

Mimics are not born knowing how to shapeshift, nor can they imitate an object perfectly on sight: they learn through experience and observation (usually by extending an "eye" on a pseudopod to look at themselves). The more a Mimic has practiced a particular form, the quicker it is able to take that shape and the more accurate the imitation will be. Young Mimics can take a few hours taking on a new form; more experienced ones can adopt a shape in seconds.

Mimics can pass the mirror test, and learn much faster when they have a mirror available.

One method comes to mind immediately:

Mimic Treats --- your mimics are of canine intelligence, sociability and are able to learn. I'd suggest finding out what it is mimics like best to eat (probably small to midsized rodents (squirrels, rabbits, field mice) and scavengers. Just make up a couple packets of rabbitsnax and whenever your mimic tries to mimic whatever it is you'd like him to mimic, you pop a rabbitsnax down his gullet!

Eventually, you might also train him to eat more delicately from your hand. Without actually sliming you and trying to eat you actual hand!

It is absolutely possible and has been done.

Stage 1 - Selective breeding

Domestic dogs are known to have descended from wolves. The exact how and why can only be guessed at. However we know from a famous experiment with Siberian foxes that domesticated behaviour can be selected for.

In the 1950s a Soviet geneticist began an experiment in guided
evolution. He wanted to show how domestication works

The method is very simple. Reject or kill the most human-aggressive animals and breed from the least aggressive and most compliant.

In the case of the domestic dog we know that this process wasn't so straightforward. Dogs were bred to hunt, to run, to guard and so on. Thus many breeds will still be aggressive unless trained not to be.

Results can start to be seen quite quickly over just a few generations.

Stage 2 - Training

Almost any (if not every) intelligent animal can be trained by operant conditioning

Operant conditioning is a method of learning that occurs through
rewards and punishments for behavior. Through operant conditioning, an
individual makes an association between a particular behavior and a
consequence (Skinner, 1938).

These days punishment is considered unnecessary most of the time and nearly everything can be achieved with rewards. Note that punishment does not necessarily mean violence - it could mean withholding a treat for example. With many dogs, a stern 'No!' will be sufficient punishment to stop an undesired behaviour.

There are big problems with training a wild carnivore (and some herbivores) without having bred for domestication. We regularly hear about trainers of big cats and of bears being seriously injured or killed. This is because no amount of training will on its own overcome natural instincts. Wild carnivores often fight and injure each other.

If you search for 'bear kills trainer' then you'll find plenty of examples.
