Well, it does do the monkey paw thing, to a small extent. The coffee pot still grants wishes, we know it does, it just doesn't perform impossible wishes. We've only see it give off a ferret (which I will address in a moment) and never seen it actually do a wish that worked instantly. The card of the artifact says it "grants wishes in unpredictable ways." The true downside of this artifact may not actually be its ability to create these small creatures.

That said, Howard Carter was the famous egyptologist who discovered the tomb of King Tutankhamen, but that was after nearly a decade of what was largely fruitless results. Ferrets in Egyptian times were thought to be extremely helpful at clearing out rodents, though admittedly there is very little biological evidence to support their domestication now. The ferret manifestation may really just be the coffee pot being unfamiliar with the wish, and thus just giving an Egyptian gift of "here, have it, this is helpful" due to Carter's strong connection with the country.

As far as Newton is concerened here, we don't know where the ferret comes from. I'd be willing to suppose the ferret is moved, apparated, from one spot to inside the kettle. Newton's 3rd Law for this unique quirk could be the ferret's puff of smoke from this transferral - as the ferret is moved from one destination to another, a vaccum is created and pulls air into the space, creating a rush of air molecules that rub together and create a puff of smoke.

But like I said, the downside of the artifact is likely not the ferret, which is rather the limitation of the artifact, like how the energy from the musicbox had to be held inside a human body.
