Cats (e.g., housecats) are independent, solitary creatures (notwithstanding the notable exception of prides of lions). Programmers (especially those who gravitate to "open-source" programming) tend to be independent, solitary creatures. Neither cats (even lions) nor programmers are easily herded. They are prone to rushing off in all directions as the whim strikes. Managing a non-trivial project with independent, solitary programmers is Excedrin Headache #1024.  - Meme Engineer -

To herd cats, use the engineer techno-lust - i.e. just use laser pointers.
