An article by the NIH discusses on how more testing on domestic cat diseases are being done. There are around 33 genes that have 50 different mutations in which result in health problems or physical appearance within a cat. Commercial laboratories are able perform cat genetic diagnostics, which can then allow vets and pet owners to receive DNA test results. The DNA can be obtained simply by a buccal swab or cytological brush and sent to any lab in the world. These can identify identify whether the cat is a carrier of any trait, predict incidence of a trait showing up, and then create possible treatments. The article further discusses genetic tests for domestic cat, potential sources of error for genetic testing as well as the disadvantages of DNA results in veterinary medicine. In addition, this article also emphasizes further studies on felines regarding diseases.
