my cat only pees int he litter box, but our other one, before he died was not fixed or if they are not fixed early enough they will spray(and if it smells that bad, it prob is spray)
if it is an inside cat, and it is spraying then maybe we should be looking to blame somewhere else
no, i am not saying either way, in fact i really do not like cats, but you cannot blame the cat for doing what is natural,
WE DO IT ourselves. mark our territory.
we put up fences or at least have our land surveyed
install locks and doors
we buy rings
and so on
all animals mark their territory and sho off somehow for mating reasons.
