Hey Charles,
Thanks. I did read that link. I should have written my post in that thread instead. I think the solution would possibly be to try to set traps.
My only concern is… why would they eat baited traps with peanut butter and Nutella when they have fresh cabbages for example to feast on. At the same time, am afraid that one of the cats might accidentally activate the traps and injure themselves?
I just saw today that one of our cats started to sit by a hole…
Perhaps I should try Eliot Coleman´s method of a boxed trap? I tried flooding one of the holes today… but that´s a lot of water to cover such a large area 🙁
Am also about to plant out autum/winter cabbages soon… it would be impossible to chicken wire all of them.
