I searched the forums, development list, and bug list for this bug and it wasn't listed. However, I know it is known by some because it was listed as a point to remember in the wiki.
When I cage my livestock in wooden cages they stop breeding. I have tried from multiple points. I have tried to put them all in one cage immediately. I have tried waiting a couple years and separating them by animal type. They always stop breeding though. Even when I release them, they will never breed again. Even if I don't even touch a kitten or dog, I will never get puppies or kittens again.
EDIT:
Nevermind. They have started breeding again but not until long after I removed them from their cages. Does some hidden breeding timer reset when I put them in cages? Would they begin to breed again if I left them in the cages long enough?
