Culture wise? Probably. Institution wise though…?
Our current republic was founded by de Gaule, and our constitution was written by him as well. The thing, he’s a millitary general, who (much like a good chunk of the French population at the time) held disdain toward parlementarism, due to the lack of stability of the Fourth Republic.
What that means? Our current system has much of the power concentrated in the hands of the gov (see 49.3 and to some extend 47.1 where the PM can just decide to override anu vote on law. It was something taboo, only used a fair few times before Macron, like once in 2014(?) and it ruined the PM (at the time Manuel Vals)'s carrier. Macron used it dozens of times throughout his years as President), leaving the National assembly with little manuveur than the censor motion (dissolves the current gov, but leaves the president in power).
That and Macron preparing to sell our public media and hospital to the private certainly don’t give me mich confidence in that regards if the RN were to win (’ •_•)
A collar or other physical appariments wouldn’t stop you from abducting it either. Where I come from and (I assume) in many parts of the world, cats have an electronic chip in their neck with basic info about the owner and how to contact them, which would be discovered when you bring them to the vet.
But I think that’s more of a cultural thing. Personally, I consider not letting your cat roam free in the neighbourhood (if you have the ability to let them) unjust and borderline animal abuse, close to how I would consider it if you kept your dog inside all the time.
Finally, taking a cat home out of, what, pettiness(?) sounds like a terrible idea, because beyond any notion of ethics, dealing witha cat you keep away from their territory and the people they know would be both a psycological and financial perspective. If you want to be hurtful to someone, there are easier and cheaper ways to do it than to abduct their pets.
So no, as a pet owner, abduction is really not anywhere near being a concern for me. Getting run over though? That IS a concern, particularly when cats panic. However, cats have far better hearring than we do and can hear cars from a mile away (esp when they’re familiar with them).
