Smell/Scent in Animal Transformations

[Crash Ichimonji]

"Kreb's Folley" made use of animal scents repelling formerly human lovers from one another due to changing into different species and bringing new lovers of the same species (even if they were complete strangers) together. The main male character dumps his girlfriend because she turns into a pig-woman while he becomes a dog-man. Her porcine scent is offsetting to him while his canine scent does the same to her. It goes a step further, though. The pig woman gets rancid in her body odor because of porcine burps and farts as well as her going to the bathroom stinks up the house and still sticks to her. Kinda grossed me out with the scat-portions at the end where the dog man just abandons her after she and a neighbor (a boar man) are going at it JUST like real pigs.

Other parts of the story have the guy getting horny from the scent of a female neighbor who becomes a dog woman and her scent drives him wild (and vice versa).


Edit:

I also remember in the April cat TF episode of the old Ninja Turtles cartoon had a bunch of cats following her shortly after the teleported-incident because her scent had become more feline.
