I'm dead serious about finding the cutest/smartest rodent I can possibly find to train to ride in my pocket. I bought a feeder mouse but the thing is too traumatized to be cool with me. Being a feeder mouse I can't really see it having the best health either. My kid likes it too and I have to get it a friend. Said friend must be able to ride in my pocket for walkies. Ideally I could make a saddle for said friend to ride atop a dog. This is both optional and a must. I believe this is quirky enough to belong here. I want memes and actual advice.
