"A Dream You Wish You Could Have"

This is the cat food we buy for Delilah.¹ Note the copy (in front of the trippy looking cat):

"Pop open. A dream you wish you could have."

What does that mean? "A dream you wish you could have." Does "you" refer to the cat? To me? And the cat/I wish to have the dream? Or do they mean the cat/I wish to have the object of that dream (presumably highly desirable cat food)? And if they mean the cat food, then why "wish you could have"? The cat/I easily can have it. I bought it. It's sitting right there. I can pop open a can, and the cat/I could easily gobble down the contents. No problem. No "wish" involved.

It sounds like something written in another language and then badly translated. Weird.
