what did you do to prepare?
If you have a problem with animals jumping your fence, do a google search for a coyote roller. It is a four foot piece of pipe with attachments on both ends the mount to the fence and allow the pipe roll. If an animal tries to get a grip on the top of the fence to jump over the roller spins and they can't get over.
A friend of mine has a one year old german shepard that kept jumping her fence and roaming the neighborhood, she put up four of these rollers where the dog was climbing and she hasn't gone for a stroll since.
The guy sells them very cheaply, I think it was 100$ for the four pieces.
