Sentry Understands Anxious Pets

Sentry uses pheromone technology to effectively change your pet’s behavior. With the help of their products, good behavior is right around the corner.

Questions & Answers

9 Customer Questions

Do you feed these all at once or should they be spread throughout the day?

Answer by Chewy • Apr 09, 2024
Based on your pet’s weight, it is recommended to administer the supplements all at once.

Will these work for a cat that goes full freakout when clipping her nails?

Answer by Chewy • Dec 26, 2023
This supplement is intended to help support cats during stressful situations and may help soothe your cat while they get their nails trimmed.

Where are they made and where are the ingredients sourced?

Answer by Chewy • Apr 02, 2024
This supplement is sourced and made in the USA.

How long do the effects last?

Answer by Chewy • Feb 02, 2025
This product can be given before and during an event. Ideally, give it 30 minutes prior to the event. You can also place your cat in a calm area such as a kennel or a room where he or she can feel safe. Please note, all cats are different. From studies, we have seen calming effects ranging from 10-30 minutes.

My cat hates being in her carrier and in the car. I bought these to hopefully make her mellow enough to transport without feeling like I was kidnapping her. She didn’t really like the taste, so I had to mix them in with other treats for her to eat and even after eating the full recommended amount, she was willing to fight me tooth and claw about getting in her carrier. She let me know how unhappy she was about it the whole car ride.

The chews are calming and tasty.

These definitely calm my stressed cat. I didn’t know what to expect , but was surprised to find my restless cat sound asleep that evening. He was obviously exhausted from stress which partially causes his FLUTD. He gets the recommended dose, exactly. It was difficult to choose a product, I read the ingredients for many different ones. Sentry Calming Chews had ingredients that I felt comfortable giving James.

Helps with aggressive behavior

My cat loves these treats so much. I had to put them in a jar as she doesn’t have the best track record with treats in resealable bags. Every time I open the jar

My cat loves these treats so much. I had to put them in a jar as she doesn’t have the best track record with treats in resealable bags. Every time I open the jar she comes running and looks at me with the most upset eyes when I’m closing the jar. I have to limit her intake cause she’d eat the whole bag if she could. My cat has been very aggressive towards my parents cats since we moved in and these treats have helped her be nicer towards the “others”. She’s much more calm and is even more lovey dovey with me after having had some. She’s 11lbs and I usually give her 3-5 treats so she’s not too loopy, but they are still effective. I’ve had trouble with getting her to eat other calming treats in the past as they are thick and chewy, but these are much more like “Temptation treats”, which she loves.

I am traveling in an RV, on the road every few days. My cat doesn't like traveling days, which I understand. Once I tried these calming treats, she doesn't mind traveling anymore. It's not stressful on her so she can relax and nap peacefully.

This really helped with regulating our cat's sleep/play schedule. It helps her get enough sleep at night so we can also get sleep. And now she sleeps more at night and plays more during the morning/evening! She also loves the taste.

These work !

I previously tried two other calming chews and my kitty would not touch them. He is happy about the small size and crunchiness of these - and they do work !

Cat loves them!!!

Cat loves them so he'd give them 5 stars... I give them 4 stars because I really don't see any calming effect they have on him, but if you have cats you know that

Cat loves them so he'd give them 5 stars... I give them 4 stars because I really don't see any calming effect they have on him, but if you have cats you know that getting them to eat/try something new can be a battle.. for now I just give him the recommended dosage daily.. he actually asks for them, however when rain or storms arrive he still dives under the sofa until all is 'clear'

Works GREAT!!!

I'm not one to ever write reviews, but I have to with this. I have a 6 year old with server anxiety, he is scared of EVERYTHING!!! He had crystals from the anxiety

I'm not one to ever write reviews, but I have to with this. I have a 6 year old with server anxiety, he is scared of EVERYTHING!!! He had crystals from the anxiety and ended up with a bladder stone. He went on prescription food with calming in it. Couldn't find the food anymore. Had to get another prescription that doesn't have calming. He was hiding all the time. I ordered these calming chews and once I got the amount right, he is like a totally different cat now!! He is actually like a cat now. He's brave, walks around with his tail up, plays with the other 5 cats, and doesn't hide!! And he LOVES them!! Just got a second bag..

It works!

We had to take in two young cats after family members died with no provisions for them. The rest of our cats were pretty upset. We got the Sentry Calming collars

We had to take in two young cats after family members died with no provisions for them. The rest of our cats were pretty upset. We got the Sentry Calming collars and chews. Almost immediately the energy shifted. I won't say we are at perfect peace yet, but I feel certain these items shaved weeks off the process.
