I've talked to dogs, cows, and horses. I think I've said a few words to deer. And, the two times I saw a black bear crossing the road ahead of me. Although, technically, I don't think I talked to them - it was more a "holy s**t, a black bear!!". As I'm thinking about it, I may have talked to a few wild turkeys and I've yelled at some Canadian Geese so, again, not really a conversation. But, I haven't talked to a cat while riding a bike ...
