Aww they're sooooo cute though! Hahaha! We used to have one exactly the same & eventually he got really cheeky and was on the couch one day so I trapped the cheeky bugger and we had a new pet! Went to the pet store and spent $70 on 'necessary' mouse paraphernalia but didn't have the courage to tell the pet store owner where our new friend had come from (shame). We had him for a couple of years but he eventually died. They're pretty disgusting, I wouldn't want them running all over the house either but some of them are just to cute to kill! Embarrassed to post this now!!
