Thunderease vs Feliway: What Is the Difference?

Thunderease vs Feliway

Cats tend to display unusual behavior like urine spraying and inappropriate scratching when to anxious or stressed. Similarly, conflicts may happen in a multi-cat home.

The use of synthetic pheromones like ThunderEase or Feliway can help solving these issues by mimicking cat pheromones to make felines calm and relaxed.  They work by copying the natural feline pheromones produced by cats when they rub their face, urine mark or scratch an area. When these products are applied, they tend to calm cats down, reduce the conflict and fighting between cats, and reduce their destructive behaviors.


ThunderEase is manufactured by ThunderWorks, a Durham, North Carolina-based company known for the pet calming shirt, Thundershirt. ThunderWorks was recently acquired by Ceva Animal Health, manufacturer of Feliway and Adaptil. It is vegan-friendly and mimics cat pheromones to keep cats calm. It is odorless, drug-free, easy-to-use, clinically-proven, and can be used for both cats and kittens. 

These are the two variants of ThunderEase

The pheromones also help cats to bond with littermates and their mother. This product is ideal for multi-cat homes to stop the fighting, tension, and conflict.

3. Feliscratch 

Feliscratch redirects your cat’s inappropriate scratching into the scratching post instead of your curtains, furniture, and other household items. It may be used along with Feliway Classic Spray if the behavior has been going on for quite some time. To use, simply apply the product to the scratching post and draw two to three vertical lines. One pipette should be used in the first week and another pipette during the third and fourth weeks. 

Carefully apply the product by placing the scratching post over a sink. Apply slowly and wait for at least five minutes to allow the solution to dry before returning the post to an upright position. The marked scratching post should be placed near areas where your cat usually scratches and sleeps.

ThunderEase vs Feliway: What is the difference 

Both products are vet-recommended, clinically-proven, and safe to use. Both use synthetic cat pheromones, the facial kind and those that mama cats naturally emit. While both products attest to a 90% degree of effectiveness, some cats may respond better to either of the two. This is because each cat is unique and the severity of symptoms may also vary for each feline.

The difference between the two products is mainly in the price or cost.  ThunderEase is slightly higher in terms of price compared to Feliway. Also, the former had an unique feature that is missing in the latter, the rotating plug, which makes it convenient to use as it can fit in any outlet.
