Fair enough. I just used an image translation thing on my phone, so I'm sure you are right. But being from the border of Texas/Louisiana, the idea of mouse gumbo is also hilarious AF.
I asked my friend from Morocco. He says the cat is asking for mouse flavored "Jumbo". Jumbo is a brand of stock cubes which normally come in flavors like beef, chicken or lamb. The shopkeeper replies "que" in Spanish which means "what?"
(For non Arabic speakers, hard G does not natively exist in Arabic and different dialects use a different letter to denote a hard G, a lot of the time contextually)
