Anyone booking a kennel is trusting a stranger with an animal, usually in a hurry, usually before a flight. The one fact that matters is whether the place holds a current council boarding licence, and that is buried in local authority registers nobody reads.
Paws4Travels only lists licensed kennels and catteries, carries the official star rating, and takes the booking and payment in one pass. At capture it covered 74 licensed premises across 12 counties.
The constraint
Licence status is the product, so the listing cannot run ahead of the register. A county goes live when its premises have been verified, not when the page is ready.
