This cat has people feel-ine like opening their wallets.

People from across the nation have shelled out more than $20,000 for victims of Hurricane Harvey in exchange for a funny photo of a Brooklyn woman’s cat.

Rachel Millman, 29, of Bushwick, came up with the purr-fect idea to help people affected by the Texas storm when she realized how much her Twitter followers love photos of her 18-pound tabby cat named Jerry.

“He’s kind of a mini-celebrity among my followers,” Millman told The Post. “So I thought how many people would actually donate to see this funny picture?”

The freelance writer tweeted the prospect on Aug. 28, writing “@ me with proof of donating to a charity for south Texas and I will dm [direct message] you a photo of Jerry behaving badly.”

Requests immediately came pouring in.

“I felt really flabbergasted and pleasantly shocked,” said Millman.

As of Saturday, she had sent out nearly 300 photos of Jerry and tallied $23,492 in donation to charities, but expects that number to grow.

Millman wants to keep details of the photo a secret in order to keep donors’ interests piqued.

The cat mom also created second and third tier “rewards,” for $69 and $100 donations, which include a funny video of Jerry doing air guitar and a drawing of the big kitty.

Millman was touched by how many people jumped at the chance to help.

“I feel really fortunate to be a first hand witness to so many people being good,” she said.
