Cat will urinate in litter box but defecates on floor.
My 17-year-old cat Winnie has never used a litter box until this year. She has always gone out in the yard somewhere. But with the heavy rain in California this year she starts to act kind of desperate, so I got her a litter box. It's located in a sunroom (with the outer sliding door open to the outside). Her food and water are on the other side of the room.
The problem is that Winnie will urinate in the litter box, but she'll defecate in remote corners of the room. I've tried scooping the solids into the litter box and changing the entire litter daily but with no change. I can't tell her NO because she's stone deaf. All I can do is put her face close to the mess and lock her outside for 30 minutes. That doesn't work, either.
How can I train her to use the litter box for everything? She used to go outside when it wasn't raining. Now the floor is much more convenient. How can I break that habit?
