I had to walk around aimlessly until I found some. You then have to "heal" them. *BUT* If you find the wolves first they die if you don't find the rabbits soon enough. :( I hadn't found any foxes though. Rabbits also multiply out of control ha ha
gave up after 40 minutes because I had lost my house and my animals :/ Would be better with a map or maybe a compass to point to your house? Cute concept not fully baked.
