Oh no Sherrie! I'm sorry to hear that Winston kept escaping from his collar. It sounds like the collar was too big for him if he has a very small neck. You ordered the standard size but I would like to suggest 'petite' for his replacement. Is Winston much smaller than Anubus? Breakaway collars must be a snug fit to prevent avoidable loss. If there is enough room for the cat to get their paw between the strap and their neck then they can forcibly break the mechanism using brute force. Cats are very clever after all! Repetitive loss it due to the incorrect size 90% of the time, the other 10% accounts for real feline Houdinis. Of course the collars are designed to break open to prevent injury if the cat gets the collar caught and this can happen at any time but if it keeps happening it warrants further investigation. I will email you directly about the replacement collar for Winston so please keep an eye on your inbox. Best wishes, Sonja
