Bay Area animal shelters will offer free adoptions Saturday as part of a national campaign to find stray dogs and cats a permanent home.

The second annual “Clear the Shelters” initiative, co-sponsored by NBC and Telemundo TV stations, will take place in more than 400 shelters in 20 states.

Locally, all four Human Society Silicon Valley adoption centers—in Milpitas, San Jose, Sunnyvale and Mountain View—will participate from 10am to 6pm the day of the event. For the addresses of those locations, click here.

Santa Clara County’s animal shelter will also take part in an effort to adopt some 250 cats ad dogs. The county pound—located at 12370 Murphy Ave., in San Martin—will be open from 10am to 4pm Saturday. Side note: the county animal shelter is a Poke Stop, for anyone who wants to multitask by adopting a new pet and catching a new Pokemon.

In addition to waiving adoption fees, which normally exceed $90, participating shelters will offer free medical screenings, vaccinations and a behavioral assessment, Santa Clara County announced earlier this week.

“There are so many pets that need a loving home and will no doubt bring tremendous joy to hundreds of families,” county Supervisor Mike Wasserman said in a press release.

According to NBC, 20,000 pets were adopted during the 2015 “Clear the Shelter” campaign. Yet millions of pets remain unhoused.

“We work very hard to find permanent homes for animals that come through our shelter,” said Amy Brown, head of the county’s Consumer and Environmental Protection Agency, which oversees the shelter.

The “Clear the Shelters” event is especially important this time of year when the shelter is overwhelmed with kittens, organizers said.

“Summer is a busy time for animal shelters in Santa Clara County,” county animal shelter manager Lisa Jenkins said. “Our goal is to find forever homes for all of them.”
