When does a Turkish Van stop growing?

Turkish Van typically stops growing around three to five years of age. They can reach their full height around their first birthday but will continue to fill out and mature until they’re about three to five years old. These cats tend to take a bit longer to reach their full size compared to other breeds. 

You should switch a Turkish Van to adult food when they’re around 12 months old, but don’t be surprised if they continue to gain muscle and fill out even after that. Their growth is more gradual, especially when it comes to developing a sturdy, muscular frame.
