I've always had cats with chickens and young chicks and never had an incident. One young cat was stalking the chicks right in front of me and I just gave a correction and it never happened again. Now, I've had cats that really loved to run towards a group of hens to make them squawk and scatter just out of sheer fun...my current one does that as often as he can or he will stalk a hen and then scare her but no honest attempts to pursue or catch a bird. I love to watch them do that..never fails to bring a smile to my face! One of my toms would "round up" the chickens for me if they got out of the fence, on command! He loved that job and would just sit and smile after every last bird was back over the fence...I miss that cat.
I had a cat that would stalk the geese I use to have and no doubt she would have attacked if I didn't watch her. But boy oh boy was it payback time when they got grown. I laughed so hard one day, she hopped up on the picnic table to get away from them and they were reaching up and biting her feet. LOL
Once we lived across the road from a lady who had tons of mangy, hungry cats and they would be seriously stalking my free ranged flock...and right behind them my GP mix dog would be stalking them. When they made
their move, she would make
hers and it was vast entertainment!
I've never seen any of my cats catching rats but my dogs do, for sure, especially Jake...he's a wonderful rodent catcher and any moles, mice, ground squirrels or rats he can ferret out are quickly caught and killed. Some are consumed, but voles and moles are never consumed by our dogs or cats. Must taste pretty bad if the dog won't even eat them.
I have had several dogs that would catch mice, dig up moles, etc. And you're right, they love being outside at night. Early this morning mine were barking at something, possibly deer. I can usually tell by the bark how it's going. LOL one night I had to go check on them and I nearly stepped on a slobber covered possum. My one dog kills everything but the other just smooches them I guess. LOL
Dogs LOVE being outside at night if they have any kind of prey drive at all...night is when it's all happening and they are predators, first and foremost. Anything that comes in their territory is warned or killed and this keeps the preds in the area knowing that a bigger predator lives there and roams at night. My dog is outside at all times and we are surrounded by woods...black bears, coyotes, bob cats and foxes are the top preds here and none will dare to come into his territory. Possums and coons are sometimes dumb enough to enter and are quickly dispatched.
Been there, done that...it ain't pretty.

Guess what? Weebles really DO fall down.
You are so right! If I had a dollar for every time I have fell outside... I'd be much better off! LOL Not perdy at all. lol
