Check the listing of available cats and kittens. Many of them are only 1 yr old. https://www.seattlehumane.org/pets/cats/ The facility is across from the T-Mobile HQ and is probably the best shelter I have seen.
Call the directory assistence at 411 or open the google or apple maps and write animal shelters in the search space, press enter and you should see a list of shelters that are close to where you live. I hope this helps. Good luck!
Maybe give them a call. They do have a few young cats from time to time. Kittens many of times. Head down then and take a look.
