Hiya everyone

Just a quick question,i have been giving my cat a treat on a sunday of fresh chicken as we having sunday roast and maybe 1 day in the week i will give her a bit of sausage and now she wont eat normal cat food.

Do i just leave her starve and she will eat it when she is hungry or do i keep trying different food.

Do i have to stop giving her a treat now i she is being this fussy?

thanks for your advice in advance xxx
