My cat will sometimes demonstrate why California allows cats to be uncollared and unlicensed and free-roaming: he kills rodents. More occasionally a lizard or bird.
This AM I was in the downstairs bathroom and noticed a live mouse at the top of the shower. He had climbed the shower-hose. He was not happy.
Most of the time I only find a fractional mouse in the shower. At least its easy to clean up.
I tried to free the climbing mouse but he got loose when I did. I have freed rabbits, mice, hummingbirds, and regular birds from cats. I hope the cat gets the mouse soon though.
Once the cat got just the tail of a lizard. Sometime later I saw the lizard in the house, and let him go.
Tried to find the Ca law. Found this amazing site

which is militant pro-cat.
This site

is cat-hostile.
There are many oppressive sites that claim cats should be indoors only. That is just wrong. They should have fluffy pillows to sleep on when they want though.
And for those that can handle it, occasional catnip in moderation.
