4 and 5 foot digs. Your making me fall off the sofa laughing. Last time I had a dig over 2. Foot was, was, was, let me see, 110 years ago. No fcker digs these days. We have robo ferrets in our area, which however are quite expensive. Mr. Ketchum will surely back me up. We have a famous Scottish friend who will give you all the info required but excuse me for being forward but they are rather little and totally without teeth. The rabbits run round and around the said ferrets with disregard. Go on Zeus give him some verbal and get him watching your videos. Jok.
