We have....a strange cat. Most cats aren't going to like strong smells like chemicals sprays and whatnot, but this cat....well, freaks out a little and starts going nuts over completely innocent smells. Mint, for example. She'll dig and dig at gum or peppermint soap in a bag. Citrus. Bring an orange anywhere near her and it's like you've put out catnip. She doesn't -hate- it...she just obsessively smells and paws at the strong scents. And using bleach? We have to keep her out of any area where it is because well, to put it as PG as I can, it causes her to be quite "trippy." Do your cats have any particular smells they hate or that makes them more curious than usual?
My cat Mouth has a very sensitive nose and also doesn't like strong smells. He really dislikes mint smells. He is the one who won't let me hide medicine in his food. He doesn't go nuts like your cat he just goes away fast. However, I have a lotion I put on my face for discolorations that they both go crazy for. The first time I put it on Ninja was trying to bite my face! I quickly learned to only put it on before going to bed. As far as cat nip is concerned, well they will both rub on it a little but Mouth doesn't go crazy like Ninja does.
All my cats have loved the smell of vanilla (icescreams mostly). And they hate lemons and oranges, they just run away as far as they can. They smell it from a few meters and run away with disgusted expression on faces
One of my cats in the past hated citrus fruits. I enjoyed teasing her, so I would cut a lemon or orange, and leave it near her. She would sniff then made the F*** NO! face and then, she would attack it! I wish I had recorded those moments. It was pretty hilarious (and mean, of me!).
My one cat seems to hate the fragrance of perfumes. He'll leave the room shortly after I use it. He will also develop respiratory issues, so I've learned that he comes first and wearing perfumes comes last. Cats I guess are like us humans. Then tend to enjoy some fragrances, and others they shy away from.
Oh, yes, I forgot of this My cats look disgusted every time I'm about to use them They can be away from me but they KNOW that will smell weird so they are sort of prepared for it and they watch me carefully in order to run away if I move to close to them
