Objects cannot be feral, but they can become feral.
They may also act with ferality.

Most objects are created for and with a particular purpose in mind. They can be said to have a purpose and intention within a well understood system. They are un-feral by design and, if they do not exist within any known framework, they remain un-designed and therefore exist as un-objects. (To counter this tendency, many objects whose use and purpose has been forgotten are classified in a special framework, namely: “Those objects whose use and purpose has been forgotten.”)

There are activities which work counter to this, but it is difficult to imagine an object deliberately made to have a not-purpose being feral: such objects require the internalization of the system to exist.

However, in networks, any system or object can develop unintended consequences and begin to exhibit a kind of agency. In this sense objects, collectively and in network, can act with ferality. They can become feral, or go feral. They can slip loose the structure and act on their own.

Only by ignoring prescribed relationships to a system and to other objects can an object be recognized as feral. This is a bit of a mystery, since recognizing the system collapses the feral-function and renders it ineffectual.

The ferality of networked objects is itself what makes the feral stance a necessity: having lost the ability to submit to the sublime, we have found it reconstructed in the networked behavior of our decidedly un-feral objects and actions. Having leashed every dog, we find ourselves caught in a web of leash.
