One of the many shelters in Kansas is in Lawrence - http://www.lawrencehumane.org/
We don't personally know any shelters in California, there are more than a few (google lists 376,000 entries) but our favorite shelter directory is http://muttcats.com/shelters/california.htm We love the name!

So, if you've got a little extra....

And don't forget, they'd be delighted with a gift any time, for any reason.
