I adopted a stray recently (owners were traced and didn't want him back) - a very active four year old boy.
My nerves are a bit shredded by whatever his mysterious activities are when he's not at home, and I'm aware that a similar good samaritan to me might think he needs help or he might get lost. Hence a collar.
I've had two attempts. Both times he's come home without wearing the (breakaway) collar. Last night's also included a tag with a QR code, via a pet finding service called Crumb. £9 a month for that. I found that all very reassuring, but he came back without the collar. I suspect he's going through undergrowth and, appropriately, the breakaway collar is breaking away!
My more sedate past cat did occasionally lose her collar, but it was one a year rather than one a night!
Are some cats just not good candidates for collars?
Advice? He is chipped.
