Is there a list with food you don't want to feed your pet with because it changes it? I know the filled bootles with peka glade water does, but is there more?

So long as you click 'feed' and not 'use', all food is now safe to eat. c: Watch out for items with 'use' though!

Thank you for the answer

The only "odd" food I know that still exists is the Infinity berry. It doesn't disappear when you feed it and it makes the hunger 10/10, but it doesn't change your pet or anything.

Thank you for the answer

The filled bottles and flasks from the glade no longer has the feed option. It only has the use option (thankfully!)
