Hermaphroditic cat Mittens to undergo gender surgery today

The Canadian owner of a hermaphroditic cat that made global headlines last week says she should know Thursday the gender that veterinarians have chosen for Mittens.

Mittens, which was taken in as a stray by Colleen Clarke-Murphy of Heart's Desire, N.L., will undergo gender assignment surgery Thursday at the Baccalieu Trail Animal Hospital in Bay Roberts.

"I will find out what gender [the vets choose] at pre-op," Clarke-Murphy told CBC News.

"Or maybe [vets] will have to wait and see until they open [Mittens] up."

Clarke-Murphy was floored when vets told her in the fall that Mittens had the reproductive organs of both a male and female cat.

She and her family, along with friends in the community, have been raising money to help pay the $1,400 to have the cat spayed and neutered, and the cost of some reconstructive surgery.

Clarke-Murphy opted for the surgery because Mittens was experiencing problems with its bowels and having difficulties urinating.

The family already owns two other cats, one male and one female. Clarke-Murphy previously said she would prefer another female, but she would let the vets make the medical decision about Mittens's gender.
