No, you don't need to worry about your snake going hungry. From your pics, your snake looks to have excellent body weight and could go at least 6 motnhs without a meal if necessary. However, the fact that he/she took wc pinkies is a good sign. If you can find a few more, I'd recommend scenting lab pinkies with them...Just put a wc pinkie on top of a lab pinkie and let them crawl all over each other in a paper bag.) Do this a few times, and your snake should be eating lab pinkies in no time....However, your animal is large enough to take full grown mice, so I'd recommend finding a fresh DOR rodent on a desert road, taking it home and freezing it...That way, you can use it numerous times to scent pre-killed lab mice...(You'll have to thaw it out multiple times to do this, so I wouldn't recommend feeding the DOR rodent to the snake after it has been thawed and re-frozen...it is a scenting tool, NOT a feeding tool.
Get yourself a LONG pair of feeding forceps (if you don't have them already) and wiggle the scented pre-killed lab mouse within the snakes' vision to simulate a live rodent...This should probably do the trick and pretty soon you won't have to scent lab mice anymore.

-PS-It's too bad that gerbils are illegal in Ca....I've had quite a few wc rattlesnakes that couldn't turn one down as their first captive meal....If they were legal, you could keep a frozen gerbil handy to scent your rodents as well, but as they are illegal, I'll discourage this. Looks like your stuck with the fresh DOR wild rodent, but it should work just as well. Good luck.
