Bugmom, I do agree with you that within the human psyche there are people who do horrible things as you suggested and most probably are lacking in normal social behavier such as compassion, caring, love.
However, I believe when in danger, if a person has a pet, cat or dog, their first reaction would be to protect their pet.
To most people the bond between their pet and themselves is like to a degree to that between a child and parent. At least I feel that way, not sure about everybody else.
You must be very proud to have rescued all those sweet babies.
