I rescued a free roaming cat from an elderly neighbor. He fed the cat on his back porch for 12 years at 92 he had to go to assisted living and his family were going to abandon his cat. I took her home with the intention of her being an indoor cat. She wasn't happy about that so I put lattice around the bottom of my screened in porch and reinforced the screen door installed roller blinds and had a beautiful cedar raised insulated house built for her to use when weather gets cold. I live in coastal Ga and winters tend to be mild. We get nasty storms here and occasionally a hurricane I want to bring her indoor when it storms but even though I have a litter box indoors the same one she has outdoors she will pee on my couch or bed. She uses her outdoor litter box ALWAYS. What can I do to make her feel comfortable staying in and using her litter box. We are not new cat owners this is our 8th rescue all have lived to be happy and old indoor cats. This makes me feel like a failure.
