Taylor Swift My Cats Are Cash Cows!!!

Taylor Swift is going all in on this cats thing, not only starring in the "Cats" movie ... but making some cash off her actual pet cats.

Every Swiftie knows Taylor's 2 cats, Olivia Benson and Dr. Meredith Grey ... and now Taylor is making cash off their fame. She applied for a trademark, "Meredith & Olivia Swift" ... and she's already slapped it on a bunch of merch.

Taylor's website features the feline logo on shirts, earrings, pens, and makeup cases ... but the docs indicate there's way more to come. She's applied to put the kitty names on musical recordings, jewelry, handbags, cushions and pillows, clothing ... it goes on ... and on.

Most notably ... there's a possibility of a Meredith & Olivia live show ... based on Taylor's application. Brace yourself.

It was just announced Taylor's been cast in the upcoming "Cats" film, based on the play. Word is she might play Bombalurina ... the flirtatious cat who breaks up with lots of boy cats and then writes songs about them.

Okay, the flirtatious part is true. We're just guessing about the rest.
