Technically they are not pets unless they are kept in a closed system. Closed meaning that rainwater cannot land in the system among a few other metrics.
The department of fish and game have no jurisdiction or boundaries in California. They can just walk into your backyard and do whatever they please. They are the only officers in the state that can arrest or write you a ticket for anything. They can write you a ticket for fishing without a license, or fine you for parking more than 16 inches away from a curb.
It doesn't matter if they are stationed in northwest Cali. They can drive all the way down south and write someone a ticket in San Diego.
