Here is my attempt at translating the meaning to 'native' sounding English (using Google-translate):

- Owl, I don't think it was right/fair to take people's coffee...
- Well, if you want, you can go tell them "thank you" and return their pot too. They will be so happy to see you again!

(I assume owl's last sentence is sarcastic / not intended to be interpreted literally.)

Thank you!
Owl is really sarcastic a little. Why she should cares about fairness if she gets her prey in the honest hunt?
