From your list I have rosemary and lavender but also grow lilies which can be harmful to pets, I take the flower heads off as soon as they go past their best and take the stamens off any lilies cut and brought indoors.
I've only ever seen my cat, very occasionally eat grass and then only when the lawn has got to long. She will smell flowers, usually the one's I've just planted, but never eats them.
If you use a flea collar, it could be the collar which is irritating your cat, I use flea tablets during the summer, she doesn't like having them but is flea free.
I'd suggest you seek the advice of a vet, if it is an allergy they are in the best position to advise.
