Sorry but I see a mob of people gaming the system. They pride themselves on milking social services and social security for everything they can get. Not sure what an organic illness is but anybody who wants to be on the street is sick and the sickness needs to be quarantined. 
As for the dogs when the state cleared Nimitz underpass the animal shelters took in 100 dogs and 100 cats that were living underneath the viaduct including litters of puppies and litters of kittens. They were sick, dirty, covered in fleas, anemic, and unsocialized.

You're right its an aberration and a deviant lifestyle when animals mistreat animals.
