Can cat's wear the dog thundershirt?
Answer by ChewyJul 04, 2017
It's not recommended because the sizing for dogs and cats differ. For the best results, your pet should have the correct size.

If you would add a loop to clip a leash to it I will definately buy for my cats!
Answer by ChewyJan 31, 2019
This includes a removable collar. It's safe for attaching to a leash for traveling.

My cat is about 12 pounds with very long hair which makes her a little bigger. Is is better to get the large to make sure it fits, or the medium because it should fit tightly?
Answer by ChewyNov 16, 2017
The Thundershirt is designed to be tight, almost like an embracing hug.

Not escape proof but still works!

My anxious spazzing kitty is a little too good at getting out of this. It definitely works when she has it on! but it’s short lived bc once she has the chance she’ll push herself out with her hind legs. My other cat hasn’t been able to get out of it although she’s not necessarily the kitty that needs it.. I’ll still try from time to time. If your kitty is the anxious spazzing type they may be an escape artist as well. It’s worth a try and is nice to have around so I do recommend!

Really helped my feline hyperesthesia kitty.

This product has been a blessing for my cat with FHS. I’ve usually been able to hug her or use my arm to divert her episodes and over grooming / tail chasing. Recently she has self mutilated and I gave this product a try to see if it would help. It has made a world of difference for her and has significantly reduced her tail obsession. I highly recommend this product for any type of anxious cat that responds well to touch!

The jury is still out

I have a very elderly cat I adopted a few months ago and she has potty issues. I thought I'd give this a try, just to calm her down in her new environment. She barely weighs six pounds, I ordered the small size. This item is very well made of quality material and fits my cat. I do have to say that the small barely fits her, I contacted Thundershirt directly about how it is to fit. They said the small is for cats under nine pounds with a chest size of between 9-13" and you should be able to slip two fingers between the shirt and the cat. It does have a lot of velcro strap closures in case your cat doesn't like that sound. She doesn't have any issues wearing it which is surprising for a cat from a feral colony. Anyway, when she wears it she walks around just fine, if I make it snug around her body that is when she does the lay down I can't move thing. Will it calm a cat during fireworks or a storm I'm not sure.

Hear they work well

My cat flipped out by the sound of the velcro. Hide for three hours. Have placed the thundershirt with clothes that we wear around him. Still not able to get it on him

sizing not accurate

This would be the perfect thing for our cat with severe anxiety but the sizing chart is not accurate by weight. They should give more measurements. Our cat is 7 pounds and the small is too tight on him. He really needs a medium because when we put it on he can barely breath

Turns my cat into a calmer enchilada

My cat has major anxiety issues around new people, new environments, new situations, and generally if he'll ever be fed again (answer: this cat has not gone more than 8 hours without food since coming home from the shelter but he insists anyway that one day i might just starve him). The thunder vest came with simple instructions and quickly turned Kiwi from his daily I'll Never Be Fed Again Panic to Calm Enchilada With A Waddle. It doesn't cure his anxiety but when he's strapped in he just hangs out on my lap, which is way better than him running around scream-meowing in pseudo starvation despair for the three hours before every single mealtime. It does what it claims to do, even on my weirdo. Too bad I can't buy this in human size too.

Very Effective

My Sr cat has had increased Alzheimer’s/sundowner type behavior over the last few months. He will run up to the cat/baby gate and start braying at the hallway or runs up to kitchen door and does same vocalization. Now if he starts this behavior I put the shirt on him and he calms down. I leave it on an hour or so and then take it off. It has been working well.

Absolute Lifesaver, has lasted years

Our cat Gomez has had a thundershirt for years. The same one has lasted us well. When we first found him on the street at around six months old he was a lunatic. He would not let us sleep past three am. My friend suggested a thundershirt since she had the same problem with her cat. As soon as we put the jacket on him, he is brought to a place of zen and calmness. I can tell he feels better with it on too. Although he’s grown out of that phase of keeping us up, he was recently diagnosed with anxiety. The thundershirt now helps him with anxiety; I didn’t want to be administering a pill to him twice a day as prescribed. That seemed excessive. So we use the thundershirt as needed and the medication as needed. Highly recommend! He’s a ten pound Siamese and the medium jacket fits him well.

good first experience!

We have a 10 year old cat with some serious obsessive anxiety - today we had her wear the Thundershirt for 30 mins. She spent the 30 mins pretending she could no longer walk (haha!) and once we took the Thundershirt she has been much more chilled out this evening. We plan on having her wear it for 30 mins every day but so far so good!

Velcro noise scares my cats

I tried this on all four of my cats. The sound of the velcro disturbed them. Fit is strange and did not look comfortable for any of them.
