Great news for cats! [View all]

In a study published in Nature Communications, researchers have unveiled a promising alternative to traditional spaying and neutering. This gene therapy, administered through a single injection, prevented female cats from getting pregnant, even after mating with fertile males. The therapy targets anti-Müellerian hormone (AMH), a key player in the development of fetal sex organs. Injecting a modified virus carrying the AMH gene into cats’ muscle cells led to higher levels of this hormone. The result? Ovaries that remain dormant, preventing the release of eggs.

The study involved six female cats, with three receiving a high-dose therapy and three a lower dose, Science News reports. An additional three cats received a placebo for comparison. When placed with fertile males, the control group cats gave birth after a single mating session, while none of the treated cats became pregnant, even after multiple mating attempts.

While spaying and neutering have been effective in controlling cat populations, the process isn’t without its challenges. Feral cats often elude capture, making multiple trapping and surgery sessions necessary, the U.S. Department of Agriculture reports. But what if we could achieve the same results without the need for surgery?

While these results are promising, more research is needed to ensure the therapy’s safety and effectiveness. Scientists are refining the gene and its delivery method to enhance its impact and affordability. It could be at least five years before a commercial product is available.

Too bad about the timeline. We truly have an unwanted kitten crisis. I've just read about 3 new litters born in my area that no shelter has room for. Poor little babies.
