I have a friend who cares for feral cats in the parking lot of her apartment building. She feeds them but cannot take them in because she is highly allergic. My brother is a veterinarian and he supplies her with antibiotics for them when they are obviously wounded and sick. Neither one of these people are going to commit suicide over these cats or the bill for the meds.
People who care for feral cats are part of the problem. They encourage irresponsible people to dump their cats in those colonies.
