Review: This is genuinely making my life easier - When I bought this a week ago, I was honestly really skeptical about whether it would work or not, or whether or not it would even fit my super big and fat cat, but I was proved wrong in the most pleasantly surprising way possible. This sounds so click-baity but this has genuinely been such a game changer and it’s been relieving some stress in my life. — To preface — My cat, Pepper, is about 10 years old, and he’s the only cat in my house, but he used to live with more people and other cats. Now he suffers from anxiety, specifically separation anxiety, and it got so much worse when I moved into a new home with him a year ago. He howls relentlessly and routinely every day and it gets really stressful. He also paces around and bites the air. Seriously. I’ve tried basically everything. He has his own room all to himself with many toys, and I’ve tried setting playtimes for him every day, got more cat beds, healthier food, a bigger litter box, pheromones (which actually worked for a while, but it was egregiously expensive), etc., but nothing worked as immediately or as effectively as this has. — Behavior in the ThunderShirt — When I put it on him for the very first time, he was immediately purring, and he started to move languidly, almost as if he had been suddenly sedated. He was closing his eyes a lot and slow blinking. He has never once howled while wearing the ThunderShirt, and he’s very willing to have it put on him. He stands perfectly still until I’m finished— except for when he tries to (lovingly) ram his head into my legs. The ThunderShirt does make Pepper’s movements a little awkward, but it doesn’t seem to bother him. He still has a decent amount of mobility in it, compared to when I’ve put a regular harness on him in the past. He’s not able to curl up tightly in his ThunderShirt, but he’s still able to use the litter box, jump up on the couch, fit through his cat door; and in the video, he’s drinking water like normally, but you can see how he’s a little slow and clunky. — Cons — The material of the ThunderShirt unfortunately collects a build up of fur pretty quickly, but aside from that, it feels high quality, and the Velcro is strong and allows for plenty of versatility. One of the most surprising parts to me was that it actually fit Pepper comfortably. It’s snug without being strangling. The ThunderShirt is a “use as needed” kind of remedy, but I’m trying to establish routines with my cat. I put the ThunderShirt on him twice a day for an hour or two at a time, usually during times when I can’t be in the room with him. I think this will ultimately lead to the most success and the least amount of anxiety. Every cat will have different needs, so this shouldn’t be taken as an exact point of reference, but I do believe having structure would help in situations regarding feline anxiety. On another note, I honestly don’t feel safe about leaving him in his ThunderShirt unsupervised in case Pepper gets overwhelmed by it or stuck somewhere. He’s gotten his arms stuck in the neck strap before when he was trying to roll over onto his back. This has only happened once so far. Overall, I definitely recommend this product. If you’re also skeptical like I was please, please try it!!
Review: Anxious cat? Seriously try it. Pics too! - Quick backstory: -My orange cat is Sammy, he's two now, had him for about a year and a half, always happy and playful but developing fear of noises and things like that. -He was so overly playful I decided he needed a friend and after a couple months looking around I got a hyper little 6 month old kitty who is nice to everyone, cats and dogs included. -Sammy did not like her, however, and it took some time getting used to but they play together and are great friends. -Now, problem is Sammy was so stressed from this new cat that he lost a ton of weight(I was scared for him and made sure to get all sorts of blood tests and things like that, he's fine physically). And on top of the weight loss he was also extremely anxious and scared of everything. Literal scaredy-cat. -I did lots of things to try to chill him out but the pheromones did pretty much nothing(except for a spray one I use in his crate when he gets brought to the vet, which works well, but only in the crate). -I always saw dogs wearing the anxiety vests and they looked like they worked pretty well. At this point I'm already thousands of dollars deep in medical testing and pheromones and I constantly have to be careful not to scare Sammy and stress him out further, let's try a vest. -It WORKED the first wear but it works even better after a few more times. The instructions were pretty much to feed your kitty a few treats on the folded up vest so they associate it positively with food, then lay it on their back without strapping it on and let them walk around till it falls off(I did this twice)-all along Sammy seemed very unphased. I fed him about 5 treats up till now-any time he came into contact with the vest- and I then strapped him in. It was easy but I have well trained cats who (honestly) have never scratched me out of anger- sometimes accidentally during play but still rare. So this might not be super easy for everyone. Once I got him in it he did not do the flop that everyone talks about. He's psycho for the laser pointer so I had that out to distract him. Other cat locked in room so that he didn't stress out any. We played about 10-15 minutes and he was only confused two or three times(backing up like something was on him) and I just distracted him with play. Took the vest off after playing, no struggling, seemed very relaxed. Later that night we did the same thing. I left it on an extra ten minutes while he and my other cat played. I removed it again. -We are at the point now where he just wears it most of the day. I have to say it's amazing. It's like I hit the off button on his anxiety. He was so spazzy that if I walked too quickly towards him when he was lying down, he would bolt away in pure fear until he realized he wasn't about to be murdered. Flight reaction 24/7. I should mention he's all indoor so he's never had a threat to his life to have this kind of fear. NOW seriously I could drive my car through the house and he'd be like "that's neat." (Not that he's apathetic or depressed lol, just that it's taking a lot more of a scary stimulus to make him jolt up or be afraid). So, random pros and cons at the end here CONS: -Sammy kind of gets Hat-Hair when he wears it for a couple hours. --- Solution: I give him a quick brushing when I take it off and he fixes it himself when I'm done. -it MIGHT get hot in the summer. He is pure indoor but I live in California and sometimes the heat strikes. I feel like I should note that the material is shockingly breathable. I would compare it to a thick under armor shirt, that kind of sporty material. I really like the material, this is a very high quality vest, BUT it will probably be coming off if temps go above 80F inside. -Slight risk of it getting stuck on something and slight choking risk because it has the neck strap(Velcro that most cats would be strong enough to kick off if they got adrenaline). I haven't seen any risk truly but i am aware it is there, so I will simply take it off of him if I am leaving the house. PROS: -It worked and WELL. -Material is high quality, looks like it will last a few years. -It looks pretty adjustable if you have a fat cat. Sammy is skinny and I bring it pretty tight on him(two fingers still fit under every edge and he does not act uncomfortable). ---side note: Sammy is about 8 pounds but he should be about 10-11 when he gets fattened back up. See pictures for how it fit him. -Sammy still has FULL mobility. Runs, jumps high, plays, poops, you name it. Took him a few times to learn how to jump up high while wearing it but no big deal. Final picture is him sleeping next to me literally the entire time I was writing this review(about an hour lol) Anyways, it worked for me. I will probably update this in a few months when Sammy hopefully fattens back out :) thanks for reading. PS since it's not that easy to tell if a review on desertcart is real any more(including most of the thundershirt reviews lol) I purchased this vest cash and believe it's worth the 40$. It was NOT given to me free to review, and I do NOT work for thundershirt.

## Questions & Answers

**Q: sizing**
A: The size recommended by the manufacturers was incorrect.  I bought a medium size shirt for a cat who is roughly 11-12 lbs and it was too small.

**Q: What size to buy?**
A: SIZE	 WEIGHTS	          < 9 LBSM	          9 - 13 LBSL	          > 13 LBSThis is how I found out what size to buys. The thoundershirt does work good. Hope this help you

**Q: Can you attach a leash to it?**
A: You won't be able to walk your cat on a leash because the shirt is too relaxing. You'll have to carry your cat.

**Q: My cat screams and cries all the way to the vet and undergoes terrible stress.  He's fine when we get there.  Will the Thundershirt help?**
A: Probably. My cat has the cat version of Alzheimer's. When he starts howling at the top of his lungs, I put him in the shirt he stops howling and flops over. He seems OK for a while after that and I take the shirt off after about 15 minutes. This cat becomes Catzilla when taken to the vet and the shirt reduces the screaming and conniption fits by about 50%. It was worth the money.

### ⭐⭐⭐⭐⭐ Review
*by A***C on August 6, 2025*

I’ve tried everything for my anxious cat. The behaviours he shows are extensive, including separation anxiety - specifically pawing at my door when I’m working in my office; pooping on the floor outside the bin, increased vocalization, dominating his brothers and attacking his sister cat. I’ve tried Prozac., other herbal remedies such as zylkene etc, feliway, even seeing a behaviourist and nothing worked! The thunder shirt I put on him and within 10 minutes he’s calm, he is quiet, and the problem behaviour has disappeared. Unfortunately, I’ll have to wear it while I’m awake to help with the litter bin issues as as soon as I take it off, he poops on the floor again. I wish I knew about this product sooner.. I am going to test it out slowly with the other cat who he has been separated from for five years because they do not get along. I may even try one for her too as she is a very picky eater and will not take any of the herbal remedies!
