Roller Coaster Tycoon 3: Wild! is an add-on for Roller Coaster Tycoon 3 that adds zoo animals to the roster of attractions available to park builders. However, animals come with their own challenges. The more animals you add to your park, the more you need to take care of the creatures' health. If your animals become ill, there are a few ways to get them back to health.
Click on the animal to bring up the beast's menu.
Click the "Stats" icon, which is the second icon from the right. If the chart's "Habitat," "Hunger," "Thirst," "Social" or "Cleanliness" sections display a low rating, these will need to be attended to for the animal's health to improve.
Move the animal to a larger enclosure to fix a low "Habitat" rating. Or, if you have the space around the animal's existing pen, move the habitat's fences out to increase the size of the pen.
Increase the frequency that your animal trainers are set to feed your animals to fix a low "Hunger" or "Thirst" score. If this doesn't fix the problem, build extra pens for your animals so they do not have to share food or water.
Change the amount of animals in a sick animal's pen to fix a low "Social" score. Different animals have different requirements for a high "Social" rating: Apes' "Social" score increases with more companions, whereas pandas' score will go down if there are more than three pandas to a pen. Experiment with different animal populations to get the "Social" score right.
Hire more trainers to fix a low "Cleanliness" score. Click on one of the new trainers and assign them exclusively to cage-cleaning duties to have them increase the hygiene within your animals' enclosures.
