Yes, specific aspects of AIT can be used with any animals whose behaviour and psychology are affected by their emotions.
AIT is more effective when working distantly, making it possible to treat wild, sick or traumatized animals that could otherwise not be approached or touched.
Amongst domestic animals, I have found horses the most responsive as, being herd (and particularly prey) animals, they have an instinctively high emotional response to events and situations around them.
Where there has been past trauma, neglect, abuse or abandonment, dogs also respond well, especially where there is ongoing, kind, consistent behavioural training alongside.
Results with any domestic animal may also depend on how interconnected the human and animal's problem is, or has become, and on how open we are to making positive changes within ourselves. Sometimes this can just mean learning to stop feeling sorry for our animal, or stop projecting negative mental images or fears about whatever trauma or loss we imagine or know them to have experienced. In my experience, this is made possible when we accept our animals on equal terms.
Animals that are more solitary (such as cats) can vary in their responsiveness to AIT, depending on the depth and extent of the problem, whether it's human or environment related and their individual aptitude and personality. I've found cats respond better if there is a known recent trauma, depression, or physical issues where there is an underlying emotional cause.
In summary, with any animal experiencing anxiety or trauma-related problems, AIT can help to resolve underlying issues, significantly reduce the level of symptoms experienced, and make rehabilitation and ongoing training more rapid, rewarding and effective. The extent of any change depends very much on an individual animal's emotional intelligence and its ability or desire to connect with and trust a human to help to resolve the problem.
