Many things the internet will tell you exist in Japan are still not the norm around here. I’ve been here a decade and have come across traffic warning signs for deer, cattle, tanuki (raccoon dogs) and in the mountains for bears, never for cats. So these are irregular signs. The one on the left strikes me as one given special dispensation for by the authorities to prevent accidents on a public road, maybe even in just one village that’s overrun with ferrals. The writing underneath just reads look out for animals. The one on the right looks to me like it could just be on private property somewhere.
Compare: In America they have presidents carved into mountains! Factually not incorrect but misleading, as it’s just four of them and they’re all in the same place.
lol, that second sign is amazing. Beautiful graphic. Beware cats flying out!

Or you know, don’t let cats outside
You know, a lot of that research behind that is rather dubious and has conflicting evidence.
Wildlife impacts of free-roaming cats: Estimates vs. evidence
The sign doesn’t say that, it’s just an animal warning sign like the deer warning sign you see in the US.
I mean, theoretically, deer warning signs are asking you to slow down for deer. Just because few people actually do so doesn’t mean that’s not the purpose of the signs…
The one on the right does reference cats specifically. The writing under the one on the left just references animals.
