This garden is in a sort of remote location.
Nothing would make a cat stay there.
Also, I do not want cat urine in my herbs and stuff.
And cats hunt the native birds, which sucks.
Holzer uses the pigs/chickens for plowing, before he plants.
That does make some sense - I was joking.
While pea shoots are tasty, they do not keep as bird feed :P
I have done my share of work as a farm hand and fruit picker in the commercial sector. Unless you have great marketing channels, harvesting random stuff, at random times in random quantities is not profitable. Even in my small garden here, it 'pays off' to have everything tidy. I have tried all methods, really ...
At this point, I could write a book about it :D
