11:49 AM PT -- The owner of the cat who claimed this DoorDash driver had stolen his cat is now setting the record straight -- saying the kitty is safe and sound ... and that it was not in fact jacked.

Odwin writes, "omg yall… Milo was not catnapped by the driver HES OKAY he just went on an adventure rq." It's a good thing he clarified -- because his post, which has since gone viral, sure made it seem like the cat had actually gotten taken. Talk about April Fool's, huh?

A DoorDash driver appeared to steal a customer's cat right in the middle of a delivery -- at least that's what the purported owner is claiming ... and he seems to have video proof.

A guy named Odwin -- who seems to live in Vegas, at least according to his social pages -- posted a video Sunday with a pretty damning claim ... and just as compelling footage, accusing what looks to be a DoorDash contractor dropping off some grub at his house.

The video is taken from a Ring cam ... and you see what's presumed to be a food delivery person -- Odwin says it's DoorDash, FWIW -- and he strolls on up to the front porch.

He puts a bag of food and a drink he's also carrying down on the ground ... and quickly becomes distracted by a kitty that's rolling up right next to him. The man in the video doesn't even think twice before picking up the cat and attempting to leave with it.

As you can see, he takes a photo of the food delivery with the cat in his arm, and he starts to back away. It looks like the cat fidgets a bit and he puts it down, seemingly ready to walk away from it. But a moment later ... the guy swoops it back up again and leaves with feline.

Odwin hasn't posted any further updates -- which is leading some to believe this might perhaps be staged or not real. However, on its face ... it looks like a straight cat-napping.

The cat owner has posted his cat before -- whose name is Milo -- so there doesn't seem to be any doubt this is his pet. At this point, the only real question is ... how can someone be so freaking brazen???

We've tried reaching out to Odwin for comment, and DoorDash too ... no word back yet.
