If they valued animal welfare, they wouldn’t allow cats outdoors. They are menace to local wildlife and biodiversity.
"We estimate that free-ranging domestic cats kill 1.3–4.0 billion birds and 6.3–22.3 billion mammals annually."
"may exceed all other sources of anthropogenic mortality of US birds and mammals"

We have a cat that was rescued from a neglectful neighbour. We were shocked one night when it turned up at our back door with a live pet rabbit is had nabbed from a house a few doors away. Thankfully the cat mostly has since caught non-native mice and grasshoppers since (that we are aware of).
The best conservation efforts at restoring native animal populations in Australia have been achieved through cat and fox proof fencing followed by trapping, baiting and shooting programs:
Interesting. I once had a golden retriever bring us a baby rabbit from the woods. But he brought it to us in a nurturing way, as if to being it to us for help, not for dinner.
Just another way dogs and cats are different, I guess.
I don't think keeping cats in their indoor "native habitat" will undo millennia of Old World having outdoor cats. Feel free to look up Switzerland's protection of cats instead.
In the UK garden birds are on the incline which would be counter to the general public argument that (paraphrasing here) “pet cats are killing all the birds”.
The declining bird population as whole is put down to other factors such has changes to how we farm food, decreasing hedgerows, basically us humans ripping out the birds habitats and not our cats murdering them.
Where I live small rodents are a pest, there is a large number of them and we want to control their number. Cats will stick to their learnt hunting behaviour. If they learn to hunt rodents when they are young then that’s what they will focus on hunting in their adult life’s. So in my area my cat mainly hunts rodents (comparing the numbers of mice she brings home compared to the number of birds she has). So as a kitten (and though out it’s life) play with ground based hunting toys instead of airborne toys. Get them a bell on their collar, and change it up ever now and then.
Now... Am I going to say that this is the case in all countries? Nope. Let’s take Australia where the feral cat population is vastly growing which is causing harm to the native rodent population, but that’s been blamed on the feral population and are being culled and not the domestic cats living with humans.
