Veterinary expert Leslie Lyons pointed out in an article in the journal Genetic Trends that cats have similar genomes to humans. Cats have the potential to become a valuable model creature for geneticists! "The genome of a dog or mouse has rearranged chromosomes, which is very different from that of humans, but the genes of domestic cats are about the same size as humans, and their genomes are very organized and regular," Lyons said. "When we find that there are more similar spacing between genes in animals and the order of genes is the same, maybe this will help us decipher the human situation," Lyons said. "It is expensive to use primates, but cats' affordability and meek nature make them one of the most viable animals to understand the human genome." Another reason why cats can inspire the human genome is that we have the technology to clone cats and make genetically modified cats. The first cloned cat Cc (the abbreviation of CopyCat) was born in 2001. Its cell donor is a typical three-cat cat with black, orange and white hair, but Cc's hair does not have any orange color, contrary to Mendel's law and other basic genetic principles.

Cats can also play a role in precision medicine for genetic diseases, where researchers do not treat symptoms, but repair the actual genes and gene role. For example, cats of certain breeds are prone to the genetic disease of polycystic kidney, which also plagues humans. If we could use precision medicine to treat this disease in cats, we might be able to apply these experiences to us, Lyons wrote.
