Most states have SOME "form" of checking/testing emissions, operating without ALL emission related equipment in place AND operating can be a hassle.
Myself, I am lucky to be just outside a county that DOES do full emissions testing, my county only requires the safety inspection mechanics to merely check to make sure cats are not missing.
As far as a vehicle operating fine without Cats, you obviously do not have a newer modern emission system or you have chipped your vehicle to bypass emissions.
OPs system is on a 2003 V10, 2003 typically will only have upstream O2 sensors which are before the cats, it may appear to "work fine" without cats but the reality is without having the back pressure of the cats those sensors will report back to the engine computer INCORRECT oxygen levels. The upstream O2 sensors are what the engine computer uses to detect the fuel mixture information. This WILL affect the fuel trim which can lead to an overly "rich" fuel mixture or an overly "lean" fuel mixture. This results in burning excessive fuel (dropping mileage) and if overly lean the engine will run excessively hot and possibly damage the engine.
Many vehicles sold specifically for California before 2003 CAN have upstream AND downstream O2 sensors and without a cat in place and operating it WILL cause a check engine light to stay lit..
I know emissions systems were changed between 2003 and 2006 and our 2006 5.4 V8 had BOTH upstream and downstream O2 sensors and I can assure you, ANY malfunction of the upstream or downstream 02 sensors CAN AND WILL affect the engines performance and mileage plus set the check engine light.. Been there, done that..
As far as cats, generics are not all that expensive considering the cost of a vehicle, we paid less than $250 per cat for generics (2006 5.4 had TWO cats, one for each bank).. The generic replacements work fine, we had no issue with them..
OPs 2003, the thieves may have done the OP a favor, that is within the yrs of cats known to suffer with the rattle of death in which the internal cat structure would fail and start rattling until it clogs..
Everything back to 1996 has a downstream O2 sensor-it was required by OBD2.

CATs are a very expensive precious metal.. IF you have a planned trip this weekend I'd file with insurance and install a bypass pipe for the planned trip. When your insurance settles replace the CAT
note; some engines do not run properly without the cat and of course it's illegal to replace with bypass pipe save for testing.... Which is why I say carry a copy of the theft report and the insurance claim submission if you travel that way.

Theft is common in CA.
**************************************************************
Yes to all three.
However, Buyer Beware!!- OEM replacements *ARE* expensive!
"Generic" cats are not CARB compliant. Can't be sold in CA or NY.
They will *not* pass SMOG tests!
Poster says, "Been driving both my trucks for years with a chunk of exhaust pipe in place of the Cat."
Kinda like regularly driving 10-20 mph over the speed limit on the freeway/expressway. Works until you get caught.
Cats were not req'd on some diesel pickups (Dodge) until the 2005 model year. "Cat Delete" pipes were available from many parts suppliers. Not anymore! *IF* you can find a supplier - you must sign your life away - stating the vehicle is only used for racing purposes. A seller and/or installer will be out of business in short order w/ mega $ fine.
Try to find a (new) old style 5 gal "Jerry Can". Feds = no mas several years ago. Must have new style "spill proof" (ha ha) spout.
Note: As with CA & NY, other states (and the Feds) are adopting the CARB regs all the time. Call it what you want - but from a state perspective, besides clean air....try calling it.... *REVENUE*.
CA = Blue State. AZ = Red State - depending on urban vs rural counties, both do Smog Testing.
(Voice of a Smog Test Only operator for 20+ years.)
IMO - Skip the "plates". Wrap the cat with braided steel cable, secured at both ends - long way from the kitty. Still can be stolen, but time & effort is a thief's enemy.

He said they have created and designed their own security device to protect from future thefts. They weld a sheet underneath that protects the cat. What are your thoughts on this protection device? Thanks so much everyone!

VERY common EVERYWHERE !!...:S
Visit YouTube to view various anti-theft devices and options for same.
The cats are NOT being re-sold by salvage yards - they are destroyed to recover the precious metals.
Your comprehensive insurance (minus deductible) may cover it.
Replacement is not cheap - no matter where a replacement is sourced..:(
