Okay, I have had several cats over the years, and I have one who is sixteen and one who is three. The three year old eats the same food as my old timer ( dry kibble available all day, and half a can of wet food in the mornings). Pepper, doesn't have stinkiness issues, but the three year old, Zoey? Well, I have started to refer to her as "toxic waste butt". When she uses the cat potty, I could seriously throw up.
I am going to deny her wet food from now on and see if that helps, but it's so weird. No other cat has ever stunk us out so consistently in my life. I know this is a weird post, but we just cleaned out the litter box and I am still grossed out, and this IS the random ramblings, so, well...yeah...
