If a cat shelter is the most important cause in your life, you have no empathy for your fellow man or woman. The suffering of men, women and children is ALWAYS more important than the suffering of dumb animals, however regrettable the later may be. If you can give your time and money to aid animals, but not to aid your fellow humans, then you are a psychopath, and are to be pitied as an emotional cripple. Sorry, but people come first, if you are sane.
