This is a picture of some ducks that live in the Wandle River near my house.
The way I see it; ducks are pretty annoying:
1. The live in the water most of the time, so you can't chase them. 2. They usually come in pairs so they help each other keep watch. 3. The make loud quacking noises, so if they spot me on the bank they warn all the other birds as well. 4. They fly very high and fast which makes them doubly difficult to catch. 5. Even if I could catch them the are probably too big to eat.
I don't have any of these problems with cat munchies.
