For over a decade, Sentry has worked with leading pet experts and top universities, researching effective ways to help pets lead happier, less stressful lives.

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.

Change the Behavior, Not the Pet

Pets can’t talk, so they show they’re scared, frustrated, or not feeling well by changing their behavior. Give them the help they need for excessive barking or meowing, jumping on guests, licking, scratching, and spraying with the Sentry line of behavior products.

Sentry pheromone technology helps promote balanced behavior with science-backed solutions. Help your pet stay cool, calm, and collected with Sentry Behavior.

These calming treats work wonders on my 2 adult cats! The girl is a shelter rescue with anxiety. The male, my big boy, is a high-strung overactive rescue also, but he is picky in a kinda mean way. I give each cat about 10-12 pieces(based on their weight as directed) after the morning meal and it helps them relax and by 10a, they are asleep till 5-6pm. Then they are the normal night owls as cats tend to be. I don't normally give these treats daily or more than once a day because they work. They also love the flavors. So, this product works wonders for my 2 adult cats.

The first time we got these as a gift for our skittish girl. She loved them! We bought a bag after we ran out of the gifted bag. I don't know if it is the lot or what but they are too dry and she won't eat them. They are supposed to have a creamy center and they are just dry and hard as a rock so she spits them out. Disappointed to say the least.

Gave my cat 2 of the chews as a test (she is 7lbs) at night. The next day she had terrible diarrhea. She is typically not sensitive to changes in food/treats so this was surprising. Can’t really comment on the effectiveness because I did not give her an accurate dose.

Worked Great!

Milo is part Siamese and that breed are known to be very vocal and needy. He's been on Prozac before. These Calming Chews certainly help him without the side effects

He gets very excited in the morning and chases all the pets and knocks over things. I give him 3 med treats and he slows down. I need to keep the pouch in a closed drawer because I found him chewing on the pouch. He actually tries to get into the drawer.

I had 3 that ate them, one would not. Seemed to notice a difference in the 3 that did. Now have only 2 that will eat them again. They are very small and I gave each one 4. Tried them just before a 13 hour move that they will be taking. They may not work on that much stress, but by then hope I can get some down all of the cats.

Helped my cat’s aggression

Made a real difference pretty soon after starting to give daily. Out of character aggressive tendencies started recently. Could be age related, or underlying pain

Made a real difference pretty soon after starting to give daily. Out of character aggressive tendencies started recently. Could be age related, or underlying pain. Working with vet to get to the root cause. In the meantime these are helping!

Not sure how calming

My cat loves these treats. She loves treats in general but she was trying to climb my leg when I open this bag! I have only given her 3 max so far and it seems to help with her restlessness, while I am trying to acclimate her to indoor only. It says you can give up to 10 a day depending on weight, so I didn’t want to zonk her out but even if they don’t work calming, I can use them as a special treat that’s she really likes

These calming treats work really well!

I've given my cat other brands of calming treats and they have upset her tummy. Rosie really took to these and it made her much less anxious during the loud rain
