How do I get a cat license? Currently, cat and dog owners may download the license application online at: http://www.longbeach.gov/acs/pet_license/default.asp, print, and mail the application to ACS with payment. Residents must include the current rabies certificate, proof of spay and neuter, and microchip (if applicable) to make the license current. The license will be considered temporary status until all documents are received. In 2011, the entire licensing process with option for credit card payment will be online.
