The next time you have 45 minutes available that you can watch an online documentary, I strongly encourage you to watch "Cat Crazed". It is a 45 minute documentary about the cat overpopulation problem, how certain organizations are going about resolving it, how certain individuals are going about making the problem worse and how there might actually be a solution out there! A Canadian-made solution.
Check it out. I'm not going to tell you how it ends! I had to watch all 45 minutes of it to learn what the resolution for the overpopulation problem is ... I'm not going to spoil it for you.
