It’s an even bigger gap for cats. There are 27,746 Domestic Shorthairs licensed with King County to just 6,025 licensed Domestic Mediumhairs – more than four times as many!

In total, there are more than 93,000 pets currently licensed with Regional Animal Services. License fees help support the services we provide, including animal sheltering, pet adoptions, and investigating animal cruelty. There are many benefits to you for having a licensed pet. For one, pets with a license are far more likely to be safely returned to their owner if they get lost. Licensing brings other benefits like Vacation Pet Alert, Free Ride Home, and more.
