When we moved here 3 years ago, we had a terrible time with feral cats. But over the years, they have disappeared. Things were peaceful until our next door neighbors moved in with four cats. Since then i am constantly shooing them out of our yard many times a day. All my chickens, turkeys, and ducks are penned, but it scares them when the cats hop over the fence or are sneaking up on the pens. i do let our 12 ducks roam freely when i'm home and within earshot. But the area they are in is somewhat protected by our chicken pens and chain link fences, and it is right off our back porch. i guess i figured the cats wouldn't bother a herd of large noisy ducks. i was wrong. Heard a huge commotion just a bit ago and ran out to find one of the neighbor's cats right off our porch in the middle of our quacking terrorized ducks. i yelled bloody murder and it ran off. i checked the ducks and it doesn't look like anyone is injured. i worried the most about one of our crested ducks who has neurological problems. When she gets flustered she just runs in circles or falls over and can't get up. i put a note on our neighbor's door telling them what happened and to please keep their cats out of our yard or i will be forced to use a pellet gun. Not even sure if it would be legal for me to shoot their cats, and i honestly do not want to hurt an animal. i'm just not sure what my options are, other than always keeping my pets penned up so their cats can enjoy the use of our yard. Sorry this is so long. i'm just so upset.
