I am going through yet another lost cat panic. After Basil went missing for 5 weeks 5 years ago I bought Loc8tor radio frequency collars for the 3 cats. 2 months ago I was able to locate Oliver when he was trapped in a neighbour's garage thanks to the collar. Now Ollie has gone missing again and this time the tracker is proving to be useless. Maybe he is out of range or the collar has stopped working ( unlikely as it's a new one) . Anyway, I am investigating the possibility of getting gps collars for the other 2 and of course Ollie but I don't want to wait until he returns. In the past the gps collars have seemed to be so big and clunky for cats so I haven't bothered but now I am frantic and am more motivated to actually buy something. Has anyone any opinion of their usefulness for cats? I was looking at Pawtrack online which seems more cat-friendly but it's not available until May. Any advice or opinions will be welcome. Thank you.
