CA Department of Fish & Wildlife Laws

Any person who traps furbearing mammals or nongame mammals shall obtain a trap number issued by and registered with the department. All traps, before being put into use, shall bear only the current registered trap number or numbers of the person using, or in possession of those traps. This number shall be stamped clearly on the trap or on a metal tag attached to the chain of the trap or to any part of the trap.

All furbearing and nongame mammals that are legal to trap must be immediately killed or released. Unless released, trapped animals shall be killed by shooting where local ordinances, landowners, and safety permit. This regulation does not prohibit employees of federal, state, or local government from using chemical euthanasia to dispatch trapped animals. Trapped animals must be euthanized or released immediately on site. Relocation of trapped wildlife is prohibited

(a) Use a steel-jawed leghold trap, or use any trap with saw-toothed or spiked jaws.
