Gift card for new cat owner: Petsmart? Chewy.com? Somewhere else?

I know nothing about cats but my friend is adopting a cat tomorrow and I want to gift her some money to shop. Where should I choose? She has a petsmart near her and she will be getting essentials in the morning. So petsmart seems like a good choice, but chewy.com looks like it has some fun options too, if she wants something outside of pets mart. What would you want?

Thanks!
