I originally got it when he wasn't responding to my calls in the garden.
well it worked, but it was a bit bigger then Shrap liked.
Turns out he was often just in the nextdoor garden just a 2 meters away... and he was just napping in the sun and couldn't be bothered to wake up and respond.. He's done that from day one when I couldn't find him and he was just a sleep under a cupboard.. lazy, carefree little chit.
And after a few days I could go pick it up in a neighbors yard. I thought it had come undone in a fight..
2nd time it didn't last that long , he figured out that the band was giving way (as it should since you don't want the cat to hang himself on something) because he just wanted it off..
And he scratched his neck raw to get it off, so stopped bothering him with it
But above all , After a while I was just glad to not longer track his ass, because all it did was make me nervous when i saw him near the street, and there's no way I could teach him from not going there.
I've accepted he does occasionally cross it, but he's very scared of noises and cars, so will have to trust him on it.
tracker is called Weenect.. i think it's french based.. came with a subscription , it has a cellphone connection in it.

It worked reasonably ok, but the resolution was sometimes a bit low if he was hiding somewhere. Battery conservation and small size antenna and a metal object over him... sometimes he'de be 10 meters further up then Indicated.
