Soren W., DVM

“Thundershirt is helpful in terms of making the trip to the Vet Hospital and while at the Clinic. We have seen that positive effect here with cats that we put Thundershirt on. They relax almost immediately from the stress associated with a vet visit. I even use the Thundershirt at home to help calm my cat while trimming his nails.”

“I was skeptical about the effect swaddling might have on cats. But after we returned from our first use of a Thundershirt during a vet visit, I am significantly impressed with the Thundershirt! Griffin was significantly less vocal during the entire trip, much easier to handle during the exam, appeared to have a much lower heart rate than usual for a vet visit (150 BPM versus 210 BPM), and was calm enough for the vet to hear his level 2-3 heart murmur, something she hasn’t heard since Griffin was a kitten. After he was released from the travel crate at home, Griffin did not dash away to hide under furniture for hours, as he usually does. Griffin interacted comfortably with me within two minutes of getting home, and showed no lingering stress from the trip. I’m optimistic about the improvement it will make in cats’ lives.”

Cat Owner Real Stories

Thundershirt is helping many thousands of cats and their owners to relieve a wide variety of anxieties and fears. Below are just a few. Please click here to see more.


“Casper, our Persian cat which we adopted as a 5 month old kitten, has had an anxiety disorder which causes him to cry continuously through the night, starting at 3 a.m. and continuing until it is light. For the past 11 years, our vet has medicated him with Elavil (amitryptyline) a tricyclic antidepressant drug used to treat depression in humans. As the years went on, we need to continue to increase his dose. We found a partial solution in using a calming collar, which contains mother cat pheromones. However, the problem was not solved. Since buying the Thurndershirt for Casper in December, 2012, he has been quiet at night and is completely off medication. He is also much more affectionate during the day. We have observed a synergistic effect with the collar plus the shirt and continue to use both. I have recommended the Thundershirt to everyone I know with pet behavioral problems. Thank you so much for a final solution to Casper’s anxiety problem without drugs!”

Kid E. the Cat

“I just wanted to contact you to say thank you!!! We adopted our cat about 6 months ago. He was an outside cat that desperately wanted to stay an outside cat. He meowed all night, every night for months on end. Nothing calmed him. Then I saw an ad for the Thundershirt for cats. What the heck, I’ll give it a try. For the first time in over 6 months, we actually got sleep. He slept quietly at the end of the bed all night long. AND he even purred. We never hear him purr. We got up, took his shirt off and he was as happy as can be. Thank you for giving us our sleep and our sanity back!!!”

Monkey the Cat Made Brave By the Thundershirt

“Monkey’s Thundershirt has saved both she and I much stress. We just moved to a new house. I have a multi cat and dog household, where unfortunately, she is low cat on the totem pole. Monkey is also very smart and sensitive. She was starting to withdraw to the closet, and only coming out when I would retrieve her ( not her normal behavior). Then came the Thundershirt!  Now, she is out of the closet, wearing her shirt for about a half hour once in the morning, and once in the evening. She seems to have regained her sense of confidence, and she is behaving in her normal Monkey nature. I have a second shirt on order for her Mom. We are a Thundershirt family.”

Thundershirt helping Luci with Vet Visits

“I bought my aging cat, Luci her own Thundershirt because vet visits had no longer become viable. The stress it caused us was terrible, but the stress on her was just cruel and outweighed any benefit of general healthcare. Poor thing… She would panic, literally soil herself and even lose fur for up to a week after a vet visit. It had gotten so bad my husband and I agreed that we just wouldn’t even take her in anymore unless it was an EXTREME emergency, and as a responsible pet owner you can only imagine what a difficult decision that was. Then I found the website for Thundershirts. Voila! She behaved so well and was even calm and happy the minute we got home… it was like she was a completely different cat! This was the vet office’s first encounter with a Thundershirt too. I asked them why they don’t sell them in their own office because the benefit was tremendous…the gal at the front desk said she was wondering the same. Thank you very much, Thundershirts, for coming up with not just a small bit of help, but a SOLUTION.”

Wallace and his Thundershirt

“Wallace really liked his Thundershirt. Immediate calm blinking and meatloafing. Climbed a cat tree, played and ate while wearing his Thundershirt.”

Short Pump, VA


“My 8 year old cat Rickie has been terrified of thunderstorms, high winds, heavy rains all of his life. His fear seems to have increased and as he gets older. I read about the Thundershirt for dogs and cats with anxiety issues and decided to give it a try. Rickie was extremely relaxed in putting on the shirt and wearing it. No fear or hesitation when it was placed on him several times prior to needing it. In the past, Rickie would go in hiding to the darkest, smallest place he could find and he would stay there for hours shivering with a wide eyed terrified look. He is inconsolable or even allows me to hold him or prevent him from hiding. The last few times I heard threats of a storm I would put the Thundershirt on him early. When the storms came I found that Rickie did not go in to hiding. Even though his ears would perk up when he heard the thunder and heavy wind and rain he was much calmer than ever before and did not seem to be bothered or scared as in the past. The pictures were actually taken during a recent stormy evening. I am grateful for Thundershirt and will continue to put it on Rickie at threat of storms especially upon the arrival of the Spring and Summer storms here in Southeast Michigan. The Thundershirt is very well made, easy to apply and the material very soft. Thank you Thundershirt for providing relief for my sweet Rickie during a storm.”

“Thundershirt has been successful in eliminating Jack’s vocalizing in the car and at home, and reduced hiding at home. His symptoms of fear during noisy events, such as vacuuming and thunder, have been completely eliminated. He will stay in the same room now and even watch me vacuum. During thunder, he calmly sits beside me and will even sleep stretched out on my bed. He has expressed a much calmer nature while wearing his Thundershirt. I am so glad to have it.”

Lithonia, Georgia


“Mochi the cat is ready for Hurricane Irene. He is typically a very vocal cat, and the Thundershirt helps to calm him down. He’s quieter and tends to sit more while wearing his Thundershirt.”

Mac’s Story

“Mac was very difficult to handle on his first trip to the vet and had to be trapped with a blanket prior to a traumatic journey. Yesterday he wore his Thundershirt for the first time. He allowed me to pick him up and put him in the carrier with no resistance and the drive to the vet was much less stressful for him. Now we do not have to worry about the next visit. Thanks”
