It's also not a domesticated rat, so you probably should kill it.

It's not really my area of expertise as I have never personally kept rodents other than mice, but I know that there are some significant physiological differences (lifespan, body shape, and ear shape is the best tell of which kind the rat is) as well as behavioral differences. There have also been some significant genomic differences found as well, though I'm not sure how much of that could be explained by a historical divergence of breeding lines. Generally speaking it's safe to assume that you never want an undomesticated animal in your house because it will bite the poo poo out of you and piss on everything you hold dear. This is also true of some domesticated animals, but the odds are slightly more in your favor of being able to retrain them to stop doing that.
