My oldest cat was an outdoor cat but I won't let her go outside at all because 1) the other cats are strictly indoors cats, raised that way from birth 2) I'm terrified she won't come back. She is so insistent on getting out that I have to lock her up in the bedroom just to go get the mail. I took her "window" away because she yowled constantly about wanting to go out. For some time, she seemed totally obsessed. Sometimes she will pace back and forth in a circle throughout the house, constantly going back to the door. She's learned to stay away from the door but still requires being put up if I go get the mail or otherwise go outside.
I want her to be happy and secure but am I doing the right thing? If I let her out would she come back? Should I walk her on a leash? Or would it make the pacing or obsession worse?
