My Oscar doesnt eat.

Hi! This is Dahmer's owner! More than a question, I have a situation. Dahmer used to receive his food with great pleasure, but for some time now, he no longer wants to eat WHEN I AM AROUND.

He's not thin or sick, he looks very well in fact, But I feel like he's been afraid of me for a while now and I don't understand why.

He also doesn't eat as much as he used to, although he still eats he leaves a lot of his food behind.
