Hi Paulette,

If you keep her outside than you can't really blame her for using her
instincts. She needs them to live outside! She won't be harmed by
eating wild things. That's what she's supposed to eat. She sounds like
an excellent hunter - my two are pretty incompetent and mostly just
nibble on bugs. Although Callie once found a gecko! (It was released
unharmed).

Let her be, unless bringing her inside is an option and that can be
difficult with an outdoor cat. Just be vilgilant in looking for her if
she isn't around her usual haunts and make sure she gets regular
vetinary care.
