    Rated 2 out of 5 by from Breakaway function did not work! I bought the calming collar because my cat has extreme anxiety and truthfully it worked well. A cat that never sat still in my lap began sleeping in my lap on a nightly basis. Unfortunately, I came home one day to find him tangled and stuck in the collar so badly that I had to cut it off of him. Even I couldn't make the collar "breakaway". Very disappointing as the pheromones actually helped tremendously. Why does this collar have to be designed like the "old school" flea collars? Why can't it be a breakaway style like the breakaway cat id collars?? If I purchase again, I will certainly not leave it on him if I am not home!

    Rated 1 out of 5 by from DANGEROUS PRODUCT I bought two of these collars for my cats after my foster cat left to relieve some anxiety. I got home last night to find the collar stuck in my cats mouth forcing her jaw open. She had drool all over her leg because she couldn’t close her mouth and she was bleeding from scratching her face from trying to get it out of her mouth. There is no quick release or breakaway on this collar and when I tried to free her I couldn’t even get the collar to budge I had to cut it off with scissors. Cats bathe themselves and climb so this is very dangerous. I immediately cut the other one off my other cat after this happened and i will never buy this product again.

    Rated 5 out of 5 by from It worked Just put it on today our two cats who were running around like crazy and scratching at night, keeping us awake. We just moved to a new home so must be the cause and one of our cats even started biting hair off his poor brother. So far the product works. They are very calm and sleepy. I'm amazed how fast it worked and and it's working so well, I'm a little concerned how different they are. It's like they are a bit stoned, so I'm hoping they don't become zombies, because they are fun to play with and I liked their natural personality. They aren't even wanting to play much so we will see how it goes, since it's day one. We might only put on them at night or try to only use as needed.

    Rated 5 out of 5 by from Works well. I bought this collar for 2 reasons. #1 my male cat is very mean to my female cat. This works so well, they sleep on the same chair. There have still been a few episodes of him chasing her. #2 vet visits have been much better. He has a chronic condition which requires a vet visit every 6 mo. He was much better this past visit.

    Rated 5 out of 5 by from works like a miracle! I bought this collar because I have an aggressive cat, a cat who would attack all the other cats in the house; as soon as I put the collar on, I notice a big difference in his behaviour! He now rarely attacks the other cats, he plays more with them instead of fighting! This product is awesome!

    Rated 5 out of 5 by from Shelter Use We bought the Sentry collars for a few of our shelter cats that were in need of specialized enrichment. These collars in combination with behavioral modifications were able to help our cats with various problem and shelter stresses. This also helped to get them adopted much faster and our average length of stay for behavioral cats went down significantly (25.4%) It is a wonderful product if you used correctly!!! I highly recommend it, however I will say that if you are using one for your cat at home because they are having a behavioral issues realize that it does not "fix your cat" It only helps to alleviate their stress & anxiety, if they are defecating outside the litter box you need to do two things first. Take your cat to the vet and make sure it not a medical issue, and them make the assessment as to why they are doing it. Often times it is small environment changes which cause the these behaviors (Separation anxiety, new animals in the home, moved to a new house, new family member, etc.)

    Rated 5 out of 5 by from Wonderful Have one on all 3 of my cats for 2 months. Fighting has decreased and initial atempts at play have started. Use of liter boxes way up and inappropriate urination down. Let the change of collars go a couple of weeks longer than I should and bad behavior started again. So, definitely due to the collars. Thanks.

    Rated 3 out of 5 by from Seems to help I have 4 cats. One had been peeing all over the house starting in November 2014. Took him to vet; his kidneys were in the not so early stages of failure; he had no crystals but blood in urine so I altered his diet to very low protein, gave him composure type treats once a day, started him on zylkene once a day, and put one of these collars on him. Lots of behavior mod and consistency in diet over these months...and his "accidents" have decreased from 6-7 times a day to maybe once a month, and kidney deterioration has stopped. Through tests, vet discovered that his bloody urine was likely due to a stress reaction...humans get ulcers, headaches or neck aches when under stress; this cat gets an inflamed bladder lining! So all this to say that the collar is one part of an integrated system to help my Barney Fife of a cat to be calm. After I saw success with his anxiety-reduction, I also put the collar on my youngest and largest cat who is very persistent in seeking attention from the cat with issues. Big guy calmed down a lot, so that also decreased stress on the other male. I'm very thankful!
