It appears to have a time structure of it's own that is not always compatible with the normal human bio rhythm or seasons. This limitation is most often apparent in the early hours of the morning, when CAT will seem to require that the owner provide it with input at inappropriate times. Another limitation of CAT BIOS is that CAT will often seek to perform Network Neighbourhood searches at times and temperatures that are not compatible with Owner requirements. A recently observed problem is that CAT may not return from such searches when called, which may result in Owner dissatisfaction. It seems that this is a programming problem related to navigation limitations in either the recall or recognition mechanisms.
Solid input seems to be preferred if it has been pirated or obtained from unapproved sources.
Much investigation is still required into the phenomenon, as it is apparent that CAT may prefer to take input that has been designated as unfit for CAT consumption. Cooked Human input that is still hot is almost irresistible, which can be a cause of considerable domestic disharmony. These can be fatal to CAT, depending on the timing of their input. CAT is normally allergic to warm water, and contact is to be avoided. Care should be taken with small CAT subjects if they have become wet, as it can be hard to determine if the subject is a CAT or a RAT, as both appear similar when wet.
