I haven't gotten my baby yet, still preparing and deciding what kind to get but I have a few questions that I haven't seen answers to yet. To prevent him from digging under our deck how far down should I dig? and would rock or concrete block be the best to put down so he doesn't dig under it, or maybe wood? Also, I guess it's okay to leave him outside at night as long as the temperatures don't get too low. But I might feel better if he was inside at night, protective of my new baby and all. Would that upset him too much to be outside during the day and come inside at night?? How old or large should a tort be to start keeping him outside? Thanks in advance for all input!
