Sitka’s ‘little cat feet’ bigger than most


Like many rural communities, Sitka struggles to keep up with its feral cat population. However, because of the island’s limited genetic diversity, an interesting and somewhat rare genetic mutation has made its way into the feline gene pool.

Two years ago, Anna Laffrey was out for a walk on the Sitka Cross Trail, when she stumbled upon something unexpected .

“I literally thought that I saw a three-headed cat,” said Laffrey. “And I stopped on the sidewalk, and then took a step closer into the brush, and they scattered.”

It was a litter of kittens. She knew she’d have to act quickly. It was winter in Sitka, and they wouldn’t last long in the elements. Eventually, with the help of some friends, she was able to capture one of them.

“We used a butterfly net and a pot. Yeah, we picked her up with a jacket and we had a big stock pot and we kind of dropped her into the pot with blankets and took her home,” she said.

What she didn’t know when she brought home that tiny, terrified kitten is that she was a carrier of a unique genetic mutation.

When I caught up with Laffrey and her now two-year-old cat Alice they’re playing with her favorite toy: a squid-shaped fishing lure attached to a string. Her oven-mitt like paws become even more apparent as she batted wildly at the hoochie.

“She’s polydactyl. It looks like she has thumbs. She has huge paws. She can pick up a blueberry with her hand!” Laffery says.

Put simply, cats with polydactylism are born with extra digits. In Alice’s case, that means six toes on each front paw for a total of 20 toes (most cats have 18). But While Alice’s mega mitts may seem like a one-in-a-million, the mutation is actually quite common here in Sitka. According to visiting veterinarian Nicole Caraway, Sitka’s lack of genetic diversity makes it a perfect breeding ground for the dominant trait

“If one parent has it, and the other parent doesn’t, then there’s a 50% chance that all the kittens that are born will have polydactyl or extra toes,” Caraway Explained. “So because it’s a dominant trait, it is something that is basically guaranteed to be passed on. The population genetically here is smaller, so you’re going to see more of that mutation.”

While some may assume Sitka’s mutant cat population is a result of inbreeding, Caraway says the gene can and does occur in all feline populations.

“I normally work at a very busy practice in Northern California where animals are obviously less likely to be inbred, and I still see a great deal of it,” Caraway said.

No one really knows how prevalent polydactylism is on Baranof Island. There’s never been a study, but guesses range from five-percent to one-third of the population. However, according to Animal Control Officer, Jim Rodgers, there never seems to be a shortage of them at the local shelter.

I met with Rodgers at the animal shelter. On a whiteboard he pointed out the names of the kittens who’d recently been rescued, all of which were polydactyl.

While these unique felines are slinking around at a high rate in Sitka, vet Nicole Caraway says the condition seems most common on the Eastern seaboard where they were historically kept as ship cats. It’s said that sailors once believed they brought luck and that their extra claws made them expert mousers. It’s impossible to know when the first polydactyl cat made it to the shores of Sitka, but as a town full of fisherman, it only seems right that these funky-footed cats should call this place home.
