Domesticated ferrets are to known to die fairly quickly if they escape to the wild. They have no hunting instincts. If you are worried about feral animals, why would you allow cats but not ferrets?
Ecologically speaking, we shouldn't. But the cat is already out of the bag, so to speak.

Seems like feral ferrets exist in Ireland: https://invasivespeciesireland.com/species-accounts/establis...
If ecological history has shown anything, it's that things shouldn't be "tried out" to see if they do indeed become an issue.
Maybe CA would have a position if they banned ferret breeding farms, but banning pet ferrets is simply dumb.
IIRC, this is done because female ferrets who go into heat can/do die if they don't mate and male ferrets will become quite hostile when near a female in heat.
