Our cat Striker is a 2 year old male but unfortunately he is causing us a lot of problems at the moment. He seems to use the tray to urinate but he doesn't use it for very long. He goes in many places around the house including on beds we provide, clothes, curtains, corners, doors etc.
We have two other cats who are very well behaved. They are male and female and all three are from the same litter. They are all house cats but they do have an outside run. They have their own room where they stay at night.
Things we've tried:
More litter trays (4 now)
Different litter type
Cleaner trays (changed and scrubbed every day)
Dirtier trays (only changed every other day)
Deterrents on preferred areas
Different cleaners on preferred areas
We had them from kittens and I think we failed to train him properly. My partner thinks it's a territory thing but I'm not so sure.
Our house stinks and we are getting desperate. We don't want to get him rehomed and we are worried about splitting them up if we do.
Does anyone have any suggestions?
