All four of my dogs hate cats -- because the only ones they know are ones that their owners let them roam around loose all the time and they like to come to our fence to aggravate my dogs. I put up a privacy fence, but they still know when they are out there.
I wind up having to take my dogs in so they will stop barking just because there are cats in my yard! I fenced about an acre but that was evidently not enough.
My biggest "pet peeve" (pun intended) is people who let their animals run loose unattended. We also have some very BIG dogs in the area who come to do their morning business in the unfenced part of our yard -- EVERY DAY! Peeeee-yoooooo! I would never dream of packing my 4 down to these people's yard to crap -- so why do they send theirs to my yard? Sorry .... I might have veered off topic a bit. Just sulking about it this morning...... Calm down, Debra Kay.... calm down...... just go scoop the horse-sized piles up AGAIN! I may mail it back this time......JK.
