I adopted two cats a year ago 1 male 8 months old and one female 2 years old they were semi feral at the time and after around 3 months they were comfortable with us and tame. They were both intended as outdoor/indoor cats however they are terrified of going outside. Last November I would leave the door open for them to explore and they would sit by the door but never go out. My male cat did take a few steps out the door but after hearing dogs bark he took of and was missing for a day and night until we found him terrified under a pile of wood. We were back to step one with taming him. now 8 months on we wanted to try again with getting them both outside. I put marbles my male cat on a harness and sot outside with him which I can do for a short amount of time then he runs back to the door. The female hates the harness so I can't do this with her. Can anyone suggest anyway to help get them outside without them disappearing again. They seem so scared that I'm worried they will never go out.
