The above image shows an example of how your pet will change as it grows up over time. Most horses and ponies will be fully grown in 35 days, sometimes much faster.
These horses and ponies may grow up into different adults by random chance - each newborn displayed below usually has a chance to grow up into around 3 - 8 different adult versions, and some might be very rare! Make sure to adopt more than one and watch them change as they grow.
