Had this 3 weeks ago, little cat turned up, no collar, so I posted on relevant SM and Next Door, no-one came forward. Had her scanned, no chip. She's only very young, but has moved herself in! We're quite a tight knit crescent, people are always posting leaflets through or knocking on to see if we've seen their lost pets. So she's here now. Even our old boy Bob has resigned himself to the fact he now has a housemate! My back door is always open, so if she had chosen or chooses to go home at some point, there's nothing to stop her. But she doesn't! I'd rather she had a good home here with us, than take her chances out there.
I don't know how they'll police people deliberately enticing cats though. Cats don't seem to be high on any priority list, even if they're run over, it doesn't need to be reported. Which is sad.
