Bob,
That's exciting that you are moving to TV. Welcome to Lower Paradise.
It is against the rules to let your pets out off leash and honestly, I think it's not a good idea in TV.
Your cats will have an adjustment to make with the move. Quite a few new TVers have posted about losing their cats when they get here. The cats get scared and hide, sometimes found days later hiding in the garage, occasionally not found.
I know you want to make the adjustment easier for your cats. In all probability your cat will adjust better to TV and feal more secure if you don't let them outdoors on their own.
Congratulations on your new home. All best wishes!
