I know the popular Rice Rats are a whole lot bigger.

California grows a lot of rice, but we don't have rice rats. The rice growers are very resistant to the concept, and apparently the Asians don't consider them tasty enough to risk eternal imprisonment to introduce then on the sly.

Most California rice goes to Japan. The Japanese say California rice is much inferior to their home grown varieties - but the airport shops carry red, white, and blue bags of California rice holding the exact maximum weight allowed to be carried into Japan. No Japanese leaves for home without a bag.

Calrose, was once an actual variety of rice. It had a relatively low water requirement. It is now no longer grown, and "Calrose" has become just a generic term for medium grain rice varieties grown here. The current varieties use a lot less water than Calrose did.
