The product should not contain an ingredient that your cat is allergic to. The type of product you choose should be ideal for your cats situation. The calming aid should be used according to the dosage recommendations and not overused as your cat may soon become intolerant to the product. The price should meet your budget, especially if you plan to regularly purchase and use the product. Check if the product is sedating, as this may not be ideal in certain instances. The product should contain no harmful ingredients or have serious side effects. If you notice that your cat has rashes, abnormal excessive itching, wheezing, or altered behaviors, you should take them to a veterinarian as they may be experiencing an allergic reaction to the product. Avoid using diffusers if your cat does not stay in one room for hours at a time, as this reduces the effectiveness of the product. Do not leave a cat wearing a calming collar unattended, as there is the risk that the collar could get stuck on an item such as a tree branch and harm your cat. In some cases, calming aids may not work for your cat and you may need to get a prescription from a veterinarian for a strong and sedating product if the situation is necessary.Image by: Nils Jacobi, ShutterstockOur Calming Aids for Cats Selection ProcessCatsters dedicated team of writers and editors collaborate with expert veterinarians, considering a wide range of factors when selecting the best calming aids for cats.
