With its patent-pending design, the new Thundershirt for Cats applies gentle, constant pressure to the torso and this pressure has a dramatic calming effect for cats if they are anxious or fearful. Thundershirt has already helped many tens of thousands of dogs around the world, and is recommended by thousands of veterinarians and dog trainers. And the early results for cats look just as impressive. Cat owners and veterinarians are amazed by the positive impact a Thundershirt can have with cats. As for why Thundershirt’s gentle pressure works to calm dogs and cats, anxiety experts believe that pressure has a calming effect on the nervous system and may release calming hormones like endorphins or ocytocins. Thundershirt is an excellent treatment for many types of cat anxiety and fear issues. For many anxieties, we recommend just putting on a Thundershirt and observing the results. You very well may see significant improvement for vet visits, travel, grooming, general fearfulness and others with no training. If your cat appears to not want to move in her Thundershirt (what we term the “Freeze & Flop”), don’t worry! Visit Thundershirt's website for instructions on how to work with this. For more complicated anxiety cases, we also recommend using Thundershirt as part of a behavior modification program.
