Planet Zoo – How to Set the grade of Food quality

How to Set the grade of Food quality  

There are three tiers of food quality available for any given enclosure. To see what tier you’re feeding the animals, click on the barrier or gate of an enclosure and check out the “Animals” section. Here, you can set the grade of food quality. Higher grades are more expensive, but the trade-off is happier animals, which is arguably the most important part of any zoo.
