In Deer Scooby, Scooby is in the catio alerting me to the fact there are two deer sitting down outside. Scooby does not like deer at all. Once he has seen them he does not eat or sleep but only runs around the house from window to window looking for them in an excited state. It takes him and me 24 hours to get over it. If I see them before he does, I go out and run them off.
