I decided to Feliway based on the reviews and do not regret it. The cat has become more relaxed and has learned not to get always the same 180 pulse.
Meanwhile, it is quite balanced and has little fear. The connector is for a month is no longer in operation, since I no longer consider it necessary. In the application time the cat has learned to come and visit clear to transform your loneliness in devotion towards us humans.
I may start in the future an application to reduce the residual fear of the cat. It now hurries but no longer, you will also older, maybe it also regulates the time. Overall, it is a lot more balanced. Is even in the way it should be :) (run away without panicking)
