Do you know a cat that lives in your community, but not in anyone's actual home? If so, you can join the thousands of people in a movement to keep these creatures healthy and happy.
First thing's first. We need to understand community cats. Many cats live out the duration of their lives without regular human contact, and it varies amongst individual cats how much interaction with people is wanted and tolerated. Some may be scared at the sight of you, and others may be desperate for your attention. The needs of each cat are different based on their socialization, especially during the time of kittenhood. Either way, all of these cats are members of the communities in which they live, and deserve care and respect.
The best thing we can do as caretakers of these creatures is to provide sources of food and shelter for them, as well as to take steps toward getting them neutered and vaccinated.
If a cat seems to be much more domesticated than feral, and enjoys human company, you can certainly adopt the animal into your home and seek appropriate medical care. Sadly, many community cats aren't feral, but instead are cats left homeless due to an owner's death or neglect.
