It depends on how you view it. If you view it as a wild animal taken from the wild, such as a deer mouse or a mouse found around the house, it would most likely cause extreme distress. However, domestic mice (fancy mice) cannot survive on their own due to their coat coloration and lack of wild instinct. It's more fair to keep them as pets than to release them into the wild where they wouldn't last more than a day or two, max. That would be considered cruel and unfair.

The Muntjac deer is known as the wild barking deer and has many subspecies. Their average lifespan is around 20 to 30 years in the wild.
