I bought these bells to put on out dog's collar so we could tell where she is and what she is doing as much as possible. They are very sturdy but not as loud as I hoped they would be. They are very well made and are worth the price.If you are interested in these bells as an accessory for your cat, then they look cute. I wouldn't rate them highly even if that had been my purpose because the color coat is easily scratched or rubbed off, leaving you with a dull metalic look after just one week of wear.If you are interested in these bells to put a stop to a bird-killer, forget it because they don't work at all. I had my doubts when I ordered these because cats stalk their prey. They sit at their favorite location, cleverly hidden from sight, patiently waiting for a bird to show up, and when it does, they pounce at such lightening speed, they reach the bird before it ever has a chance to notice a bell sound, by that point thet are hopelessly caught in your cat's mouth or claws. We witnessed this event a couple of days ago. From our window we watched Bird-Killer jump and twist himself in the air to catch a cardinal that had landed on a branch two feet above his head, near our bird feeder. Thankfully our daughter was able to run outside and set the poor bird free before any damage was done.Bird-Killer is only allowed out at night now.I give the bells two stars because they are useful for finding Killer in the morning before he can cause any mischief near the bird feeder.I bought these bells to use on the puppy I purchased for my mother. Because she is so small, she wears a cat collar with a bell. I discovered that my mother could not hear the bell that came with the collar so I bought your set of bells. I like that the bells come is 2 different sizes with 2 choices of sizes of wire attachments. The puppy is now much easier to hear as she runs around. My only issue at this point is that the color is quickly scraping off of the bell.The bells are great and they were loud but after less the a day the loop was intact but the bells had come off....need to have sturdier hooks. I had thought the loops that went on the collar would be easy to bend/brake but it is still on her collar with no bellsWas disappointed as i loved the bells!Love the assortment. I have 6 cats and the girls wear the small bells and the boys wear the large bells. I did not like that there weren't enough rings to attach the bells to the collars.I REally like these but they hang too low on my cats collars- I’m afraid they. Will get hung up on things. I had to order a new set of bells for my kitties that don’t hang down so low. The attachment is wonderful on the- so easy to attach to the collar so I wish I could keep them- cute collsrd also- I got some pink ones.The bells are small and the paint comes off after. While. But it is a good deal for the money. They do jingle. So you know where your pet is.I like this product because one of my dogs is lying and the other ones like to run around so I always know where they are.The birds are now safe and our little lad is no longer a bird murderer!We have a lot of birds on our garden and it broke my heart and our little lad was killing them.Great little product. And teddy doesn't mind the bells being around his neck.Excellent, these bells are lovely and bright and are loud compared to the bells you get on cat collars.I have put 1 large and 2 small on our 6 month olds collar and she hasn’t caught a bird since!Until she wore these bells it was a daily occurrence. It also helps when we can see her as we can hear her safe in the knowledge that’s she isn’t far away.Would highly recommend these bells.First the positives: good selection of sizes and colours. However, the quality is really quite poor. There are not enough rings for each bell and the ones that do come with it don't look very strong (although to be fair I didn't use them so they may last longer than appearances suggest.) But the main reason I bought these was to have bells that matched my cats' collars, and less than a month after putting them on the colour has almost completely worn off and they look terrible, so I've had to remove them. Not impressed and would not recommend.Bought these small bells to put on my mother's cat who is a notorious killer of anything with a pulse! The bells are loud enough and colourful enough to warn victims. Easy to fit and seem to be of a good quality. My mum informs me the cat has not brought any 'presents' into her kitchen since placing the bells on the cat's collar. Long may it last. We would recommend others to use.Still waiting for cat collar ordered same time but my dog is very happy and sounds very Christmasy. Rabbit is running to the sound of bells to greet the dog when it escapes 2 gardens over - so they're distinct enough. Daughter wants me to buy more to fit to her snow sleigh for the winter. Cat seems to like them on the dog, keeps tapping them to listen to them it appears. Tortoises seem to use them to know when to dodge the incoming dog - I've a Dutch shepherd cross he's fast the bells are distinct enough everybody knows where he is and the other pets thus get trampled less. Every body wins.
