Okay. In October I brought in a feral 10-month-old kitten with my two male neutered indoor/outdoor cats. She was extremely aggressive; I had her spayed, did proper intros, bought 2 Feliway diffusers. She has definitely calmed down, but around the time I plugged diffusers in, my 8-year-old male began spraying around the house. Coincidence? He never ever sprayed before. He's had a urinary infection a couple of years ago; but don't they usually try to squat and pee if that is the problem? Spraying sounds behavioral, and that's what terrifies me. Any advice? Otherwise, he eats normally, doesn't seem in pain, etc. I'm just curious as to whether anyone out there (and everyone in the world seems to love Feliway) has had it make situations worse rather than better.
