We have been doing some moving about at home, new furniture, old furniture and boxes all over the place. Our cat is a rather laid back one and doesn't mind the mess however, he started to get a bit more worked up and more into biting-especially us. We had to move his house and I think this upset him. To try and calm him and reassure him that his house was okay and still his we bought the Feliway Pheromone spray to help his calm and know that his stuff and house was still his. It has worked and he seems a lot better, despite still some chaos. Black cat medicines, dispatched the items quickly and safely, a great company. Many thanks from Tigs and his grateful owners.
