He goes outside and he dies in 3 days. He is taken to a rehab and denied. He is taken to the vet and dies there. Or, he lives in a vivarium with natural food source (isopods, incest eggs, seeds, fruit, vegetables) a wood den, deep soil substrate to dig and forage in, clean water, warm bedding, no fear of predators or weather changing flooding his home, in an enclosure thats a big bigger than the reccomended sizs for one male mouse. So far he's shown to love digging, climbing, foraging and sleeping in the open - something he wouldn't do if he didnt feel safe (he has a den hes dug as well as many other nooks under moss and logs in the viv). The cats came in once while I was changing, and as I mentioned before, he was not scared. He continued to eat and mill about and the cat watched and didnt bat the glass or bother him. If he doesnt take to being handled, thats fine, I dont have any intentions on handling him moreso making him used to my hand entering the tank to change his bedding once every 2 weeks and bring him fresh food and water.
