Hello chant
I live here in the countryside. Live traps are very common here.
And a cat does not starve that quickly. You can certainly leave it in the trap until the owner reports.

Hello
No, you cannot and must not. Animal protection laws apply here.
By the way, it can take weeks for a cat to be found despite flyers and so on.
There are rulings that say cats must be tolerated. Damages caused by cats must be compensated. Cat feces is not considered damage.
However, there are also rulings that restrict cat ownership to a certain number. Which does not help with the roaming radius.
It is permitted to catch animals with live traps, e.g., for the vet, neutering campaigns, etc. However, animals must be cared for, released immediately, and not abandoned.
Cats die quite quickly in these temperatures. No food also means no water.
I also live in the countryside. There are no live traps for cats; no one gets upset about cats. They are used as mouse traps. Better cat feces than a mouse plague.
