[Not getting fed. That's what caught his attention, even though it's just some animals. He knows there's a difference between a kept pet that expects to be fed by their caretaker and a wild animal that's used to hunting for itself.

Even with the groceries in his hands, he walks over to her.]

Ma'am? Excuse me- Hey, ma'am?

[It takes a bit before she notices him, but finally she turns - and is clearly surprised to see him.] 'Oh! Hello there, young man...?'

Why are you taking care of stray cats? Can't they catch mice or birds on their own?

[She gives him a sympathetic smile and reaches down to grab one of the strays, carrying it like a baby and offering the forepaws towards Yoon. He's not much of a pet person, so he's not sure what she's doing. He just stays very still.]

'Do you see their paws?'

[Yoon looks, but doesn't see anything out of the ordinary. His confusion seems clear to her.]

'They used to be housecats. I'm sure some of them are just lost, but others probably got sent away. Many of them don't have their front claws anymore.'

[That gets understanding on Yoon's face. So they can't hunt as well as they could otherwise.]
