The country star has partnered with Meow Mix cat food to help local, less fortunate families feed the house cats of New York.
"Being that my husband's severely allergic to cats – he's allergic to air, he's allergic to everything – I kind of have to get my cat fix by doing things like this," the 28-year-old tells PEOPLE.
On Wednesday, Pickler and a Meow Mix mobile sound booth will be stationed in New York City's Columbus Circle from noon until 6 p.m., inviting cat lovers and fans to record their own version of the Meow Mix jingle. For each recording, Meow Mix will donate 100 meals to the Food Bank for New York City.
"It's amazing to be a part of something that matters," says the singer. "I'm encouraging all the cat lovers out there to jump into the studio … and whoever wants to get in there can sing with me."
So what does husband Kyle Jacobs think of her furry pastime? "He is so supportive in everything that I do," she says. I'm blessed to have that support from him."
