Some questions..

Cones don't require yearly vaccinations, as they are very resiliant to all kinds of illness. Care for your cone should include a bath to remove any dust every so often, and lots of love.

Feral cones are usually very tame. It is always okay to approach a cone. The only thing to watch for is their breeders. Usually you will see them carrying stop signs and wearing reflective gear, sometimes with a tag saying something like "phone company" or "gas company." Never approach a cone when these individuals are near by. They will not understand the rescue process and may become agitated. Always use caution!
