Will you be travelling with your cat in the near future, e.g. to the vet or because you are moving house? Feliway can make the journey a lot more pleasant for your cat. Feliway is available in a spray and a vaporiser. The special odour (odourless to humans and other animals) that is used is a synthetic copy of the pheromone that cats naturally leave behind when they feel safe and comfortable in their environment.
