In our yard, the squirrels have become nocturnal. Not from my dogs but from the ferals in the back yard. Every night, all night, those squirrels screech and scratch and eat acorns and drop themon the metal roof DIRECTLY ove rour heads in bed. We dont have an attic, just boards then the metal roof pans so it sounds like shot guns going off. Birds get chased from the yard. Pretty much all little creatures are already gond because of the cats, now, when the cats get dumb and decided to enter the front yard, thats when the "murdering" begins! The ferals KNOW I have 6 dogs out there now, and 4 are APBT-
