I had a one-year-old female cat. She was a stray kitten that we adopted at eight weeks old. She is fixed and declawed in the front. I had issues with her at about three months old with trying to find a litter that she enjoyed. After trying multiple times I found a litter with an attractive in it for kittens that she liked. There is two litter boxes present. one downstairs on the first floor and one we recently added up in the office. When she was about seven months old, she went back to you using the office as a poop box. i have used multiple products to try to cover the scent but it has not worked. There is nothing medically wrong with her (was cleared by my vet) and no new stressors, although while we were away for four days she didn't poop upstairs once. Please help me.
