I have shared with I’m here on the side that I think working with an animal communicator could be particularly valuable. It’s the ideal situation – ASK the cat what’s bothering him, what he needs, why he’s acting this way. Perhaps a better arrangement can be negotiated. Or it may confirm that it’s unlikely to be resolved.
I found a discussion I had a few years ago about a similar cat – obsessed with going outside, although that one was more depressed about it. Without doing anything it would have affected his health, but he did respond very positively to the following two approaches –
1. Reiki attunement. It put him in a much better emotional frame of mind, more accepting. The Yahoo forum Reiki_On does free attunements. Just sign up on the database. The pet attunement is the third Friday of each month, so coming up this week. (I think all our pets should be attuned.)
2. A tailored flower essence combination in the Australian Bush flower essence series: Boronia (to release obsessive thoughts; to break addictive or compulsive behavior patterns); Bauhinia (resistance to change, new ideas and ways of doing things); Bottlebrush (for major turning points and transitions in life; let go of the past, accept what has changed in life, adapt and cope with the change, and move on; break old habits and addictive behavior or patterns). Boab probably also would have helped (for the possible miasmatic influence that can result in wanderlust)
