We have 3 cats, Kahlua (female, 6-7 years), Tigger (male, 3 years) and JT (male, 1 year), all fixed before they ever sprayed/marked anywhere.

I've had Kahlua since she was a kitten and Tigger was introduced to our household 2 years ago when my fiance moved in. There were no problems and everyone seemed happy. Then my fiance's parents needed to get rid of a kitten (JT) and we had him fixed around 2 months after we got him (he was around 6-8 months old). However, every now and then since JT was fixed one of the cats has been urinating on our bed, roughly 6-8 weeks in between incidents, most recently its been close to the spot where Kahlua sleeps the past few times. We can't catch who's doing it due to the infrequency it seems to be happening.

We're tired of unexpectedly having to sleep on the couch.

A couple of questions:

Is it possible for cats to start spraying after they were fixed? (JT never did before we fixed him)

What would make older cats start (if it is indeed Kahlua or Tigger)? They seem happy and playful around each other, no fighting and only rarely does Kahlua hiss at JT.

Since its so infrequent how can we catch the culprit?
