Meet Gizmo, Heated Rivalry Star Hudson Williams' Cat That Fans Are 'Obsessed' With

For a hot minute in 2026, it seemed like "Heated Rivalry" was on the tip of everyone's tongue, with the new HBO Max streaming show about the secret love affair between two male hockey players from opposing teams becoming the latest must-see TV. Now, one of the series' stars, Hudson Williams, is taking things to the next level by sharing the spotlight with his cat Gizmo, who is adorably advertising for Tiki Cat on social media.

In the quick Instagram clip, the black-and-white tuxedo cat can be seen coming out of a cat house, nicknamed "The Cottage," in a nod to "Heated Rivalry," to eat some canned cat food with the statement "everyone thinks my dad is 'tasty' 😋" displayed before announcing that Tiki Cat's mackerel and sardines are even tastier to a hungry kitty. It's one of several new reels from the cat food brand featuring Gizmo, who Williams and girlfriend Katelyn Rose often refer to as their "son" on social media.

"I'm *obsessed* with Gizmo 🐈‍⬛," said one person in the comments, revealing a general consensus among commenters. "Most handsome nepo cat 👏," stated another, as someone else jumped in to say, "So I will be buying this even though I don't have a cat 😭." Clearly, these people aren't kitten around when it comes to Gizmo's new gig!

As the adorable tuxedo cat belonging to Canadian actor Hudson Williams, Gizmo has become a familiar face on Williams' social media posts, where fans have been quick to embrace the actor's cat dad status.

The black-and-white kitty is shared by Williams and his tattoo artist girlfriend, Katelyn Rose Larson. While the furball's exact age and backstory are currently unknown, fans have noticed his growing presence in Williams' world, especially with Gizmo recently leveling up from beloved house cat to feline celeb in 2026 after landing the Tiki Cat ad campaign that has had Williams cheering on his four-legged "son" from the social media sidelines, with comments on Tiki Cat posts like, "GET YOURS GIZMO!! MY TIKI FWEAKY CAT I LOVE YOU!!!"

Of course, Gizmo's rise comes while Williams is enjoying his own major moment in the spotlight from starring in "Heated Rivalry," with the actor turning heads since late 2025, playing Shane Hollander in the TV adaptation of Rachel Reid's "Game Changers" novels. Together, the father-furry son duo is spicing up the internet with their respective star power — with Williams gearing up for Season 2 of his hit show while Gizmo wins hearts by just being a generally adorable cat caught on camera eating tasty cat food that makes mealtime more enjoyable. Could becoming one of the highest-earning celebrity pets be next?
