The one-time injection of a gene therapy could eventually be used to control cat populations.

Scientists have developed a gene therapy contraceptive for cats that could reduce the deaths of birds and mammals. The treatment is easy to administer and lasts a lifetime.

A single shot might someday replace spaying as a tool for cat-population control.

A small study uses genetic engineering with the goal of curbing vast stray feline populations.

Scientists have announced a potential new method of feline contraception that’s shown early promise: long-lasting contraceptive injections that prevent ovulation.

Single-use sterilant could eventually help curb number of homeless cats and dogs worldwide.

The long-pursued goal of a permanent, one-dose contraceptive may have been achieved in female cats and it should work in other species too

A $25 million prize awaits the discoverer of a nonsurgical sterilant for dogs and cats, but reproductive biology is complicated.

Sterilization implant launch in US eyed; research on gene-based approach advances.

It’s been the holy grail of animal welfare for decades now: A single injection or medication that will permanently and safely sterilize dogs and cats – especially cats. We may be about to achieve it.
