Scientists have found the reason for a serious sickness that affected many cats in 2023. Researchers from the University of Edinburgh found a new type of virus. This virus changed from a common cat coronavirus. It caused a disease called FIP. FIP is very easy to spread. It can also be deadly for cats. This important discovery is in a science journal called *Nature*. It helps answer questions about this sickness. Animal groups and cat owners were very worried.
Many more cats got sick with FIP starting in 2023. Sadly, many cats died from this bad illness. Doctors in Cyprus said it was a very hard time. Animals were dying very fast. Many doctors lost cats they were treating. This sickness was very bad. Animal welfare groups also said they never saw a sickness like this before. Many people were worried because so many cats died. They wanted scientists to find answers.
Dr. Charalampos Attipa and his team studied the virus. They looked closely at the virus's genes. They found that the virus changed a lot. A coronavirus that was not usually dangerous became very harmful. This change made the virus cause FIP. This new type of virus was completely new. Scientists had never seen it before anywhere in the world.
This research is very important for animal health. It is thought that about 300,000 cats in Cyprus died. This is a very sad loss for the cats on the island. The article in *Nature* is a big success. It is the first paper about a pet sickness in the journal for almost 40 years. By finding the gene change, scientists can create better tests. They can also work on treatments for the future. We need to know how a mild virus can become so dangerous. This will help protect animals everywhere.
