I have always trained at night, and I have found a solution that keeps animals aware of your presence. Go to a pet supply store and buy some of those little play balls for cats that have a little jingle bell inside. You can remove the bell and attach it somewhere on your bike, like to a toe strap that is then secured around your frt hub as a hub cleaner. It will jingle just enough so animals will here you coming and run or at least stop where they are. I always have one on the front hub or h/b stem of my training bike. I used to have a little cow bell the size of the tip of my forefinger hanging on the stem. It made just enough noise to keep animals aware of me. Eventually you will get used to it and won't even hear it. Just a practical idea.
