Cat behavior change
by Sam
(Jacksonville, FL, USA)
I have a 6 year old cat that I found when he was 3-5 weeks old. He has been neutered and sees the vet annually for shots and a check up. Recently he defecated on my bed, which he occasionally sleeps on at night at the foot. Two weeks after that "mishap", he defecated and urinated on a chair cushion in the living room. He has never done anything out of the normal since he was neutered at about 6-8 months old. He always using his litter box and it is cleaned every day and he has always been and indoor cat.
The only change I can think that might trigger something like this is there are some new outdoor cats that occasionally hang out around the house. I recently opened the window that has a box for him to sit on to look out the window, since the weather has gotten nice. I have opened that same window and the back door many times to let him see out and to air out the house some and it has never been a problem. Could it be because there are other cats around the outside or a possible illness? He acts the same as always and his urine and bowel movement seem normal.

You have hit the nail on the head I think. this behavior is known as Middening, See this page for more on this

Hopefully he will settle down after awhile once he used to the new cats being around. A period of litter training as described on the page may also help him to calm down and relax.
hope it sorts itself out soon
