The third installment in Katherine's series of personal blogs for iVillage was posted today and this week she turns her attention to a subject close to her heart - animal welfare.

Several years ago Katherine and her mother Nancy founded the Jason Debus Heigl Foundation. Chief among the organizations many endeavors has been the diligent fight to change policies, bring awareness and stop the unnecessary euthanization of healthy adoptable animals in the city and county of Los Angeles.

In her blog she questions whether society as a whole is also culpable to some degree for abandoned, forgotten and abused animals - not just the abusers, the reckless or the thoughtless - as millions of healthy adoptable companion pets are killed every year in shelters due to overcrowding.

It's easy to lose sight of humanity's capacity for compassion, but in the world of animal rescue I am reminded over and over again of how most people are inherently good and well-intentioned. That's what I force myself to focus on when despair and hopelessness starts to creep in. I choose over and over again to see people's character and integrity as my dogs do. They have set the bar high when it comes to faith, compassion, patience, loyalty and unconditional love and when I pray at night, I ask that I can follow their example more often. These remarkable creatures have put so much trust and heart into the human race: Now all we have to do is deserve it. Katherine Heigl, iVillage - January 2012
