My baby took a car ride and because of this AirTag collar we could find him. It frayed from the beginning BUT never came off . We have 3 cats . The escapee pulls collars off. This never came off. He spent two weeks in the woods, wetlands of north florida. Got into thickets and when they tried to net catch him, this never came off. When he got home the collar got a great washing and I am replacing now since we are down to threads. I ordered two more of the same, plus the adjustable slide one. Saved my boys life from a horror show. We hung iPhones from trees, and had a map of where he pinged. Quite a task but we got our boy home. Photos are of him passed out with collar, him and his friend who is getting collar also, him in trap after we finally got him, collar after about 11 months of hard wear. The collar was such an item of luck parting was hard, looks like Boa scarf now. We were always trimming loose threads but knowing it stayed on was all that mattered.
He gets to go for a walkabout daily, it is nice to know I can find him. I expect his little friend will escape so we are getting her collar now.
