Puss-boots. Feliway spray which is available from the vets, it excellent. I use it to spray the four corners of the cat box a couple of minutes before popping the cat in. The spray has a calming effect on the cat, and you can also use it to spray the legs of tables, chairs, door jambs, etc in the new house, which will help Boots to settle in. You would need to spray the things mentioned at about the level/height of the cats nose. It's a bit expensive about �21 but the little spray bottle last for ages. I also use it around the house on Fireworks night, and New year, to calm the cats, and it works well. Feliway is also available for dogs if anyone else is interested. When are you moving house? I wish you everything of the best and happiness in your new home. Please keep in touch. love Schutz.
