    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 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 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 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 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 5 out of 5 by from Try It!! My 3 year old neutered male was spraying, one spot only in plain view. He is usually a very laid back cat. Turns out he had a low grade uti and had become reluctant to use his litter box, he also appeared agitated during this time. I was confused by all this since he was indeed spraying and not simply peeing, but from all indications this is what was going on. The Sentry collar plus antibiotic and he trusts his box again and is not spraying.

    Rated 5 out of 5 by from My cat is not hiding My formally feral kitten became a full fledged house cat but feral behaviors still persisted ( hiding, distrust of footsteps, and constant checking of her environment). She would not sit on my lap but let me hold, pet her and hand feed her. After I placed this wonderful collar on her hiding has decreased markedly. She now sits in full view of all family members on an overstuffed chair. She now sits on my lap after I called her and patted the couch ( I was holding my breath but she came on her own . The satisfaction from this product is a "10". Thank you so much
