Hope you do not mind a story happened last night, Buddy outside barking like crazy a different serouis bark. I went out turned on the back light Buddy came running up all his hair was standing up on his back,he was growling charged out to the back wall. I went in the house got a flashlight & shoes on went back out Buddy still rasing hell at the back wall. I walked out huge black cat on the wall so I said shoo just laid there, I picked up a stick and gentley pushed the cat off the wall. Buddy was so happy I knew he would never eat his dinner with that cat back there it was his dinner time anyway.As I may have said before be have a Cement Business behind us they make the big cement blocks all kinds of wild life back there Hawks,Owl's fox,possoms,bats,rats,& mice & and now seems like Feral Cats heard them yellowling the other night & no telling what else is over there always worry when my little girl s Patches & Gizmo go out in the back yard. Now that we have Buddy I worry a little less all the wild life knows there is a big dog here now. It was very interesting a few years ago there was a Fox up on top of the cement block stacks at least 8 feet high the cement wall is 6 ft high the stcks are taller than the wall. The fox was just up there laying in the sun took pictures of it, have heard from neighbors a Fox family lives over there.
