I brought a spayed female stray cat, about 6-8 years old, into my house in Nov 2010. She lived with, but did not like, my other cat and dog. She never once peed outside of the box, which was a covered box with fresh step litter.
I moved in Aug 2011 and gave the cat to my mom in a cat and dog free house. I thought this would be less stressful for her as she really hated my dog and other cat. Same litter and same box. In Oct 2011 she started peeing outside the box in various locations, including right next to the litter box.
She has been brought to the vet and does not have a urinary tract problem.
We tried feliway. It did nothing.
The litter box was moved to different areas. It didn't make a difference.
Any suggestions? Why would a cat pee inside the same box with the same litter for nearly a year only to stop?
