Cats are creatures of habit and any change in their routine can produce a stress reaction. Your cat may lose their appetite, display aggressive behaviour or begin to groom excessively. If you know that there is a change taking place that may make your cat feel anxious, then you can pre-plan by giving them a calming supplement to help them through the tricky time. This could be the annual event of Bonfire Night or perhaps a trip to the vet. Moving to a new house or taking them on a journey somewhere unfamiliar are also good reasons to give your cat an herbal supplement which will allow them to feel calmer. Wormers offer tablets, liquids and gels as well as plug-in room diffusers which emit stress relieving properties into the room. There is good evidence to suggest that these supplements will give your cat comfort during anxious times.
