Flea protection product for sensitive feline skin - Any advice Options

[Yashodhara]

Dear Friends,

One of my short haired indoor cats seems to have sensitive
skin when it comes to the once a month Advantage flea protection
I place near the collar line on her skin.
I think it burns her skin or irritates it badly.

She wouldn't like me spraying topical sprays of
either essential oils or general flea sprays, so if
anyone can give advice if there is a brand
of flea protection which is easy on the skin
and is a once a month type application?

Anyway suggestions greatly appreciated.

Program, it's administered orally. You need to obtain it from a vet and dose your cat once a month, hope that helps.
