My cat is starving

So, I’m in my 50s and I haven’t had a cat since I was a teenager. Everywhere I’ve looked it says to feed the cat twice a day. Every time I feed her, she gobbles it up…wet, cat food.

She behaves like my dog, begging for food all day long like it’s the only thing she ever thinks about. She acts like she’s starving however she’s pretty healthy. Any tips on how to satisfy a cat so I can stop second-guessing myself thinking that I am starving her. She was a stray when she ended up swindling herself inside my house this winter.
