Thank you for confirming! Very sorry for your experience.
I'm not actually surprised at all that it COULD happen despite not being super common. Another member actually SAW a vulture attack one of their chickens and said they too would never have believed it had not their own eye witnessed it.
All animals are free thinking in nature.. and may try something new at any time.. if they are successful, they WILL teach it to their offspring given the chance.. As I creationist.. behaviors do evolve with time and it only takes ONE to figure it out.
My feral barn cat (at least 2nd-3rd generation feral, now trapped, fixed, released) hunts all kinds of things including squirrel and duck.. usually the babies.. I saw a nest she found this season and failed those left behind despite trying hard to save them for release. I even leave rats my (once feral but tamed) domestic cats kill but don't eat and ANY whole chicken/chick.. whatever that is dispatched or passes but not going on the table for whatever reason.. too small, too you, not enough time.. It's very much a risk I take, noting birds are locked up with multiple layers of security at night due to very high likelihood of predator visitation AND my daytime pasture is more dominated by human and canine activity.
As you see roosters are only mostly helpful during the daytime, if even then. Most often they are just a front line sacrifice. They are NO match, even if they try for most of my local predators.
I would not say the cat didn't fear you.. just that it didn't respond in a manner that you perceived as fearful. If cornered with no where to go or means of avoidance they will fight.. if a light is suddenly blinding them or they can't see their escape route.. hissing, spitting, clawing, even growling viciously to CONVINCE you this pint sized animal is a threat and you should back off... completely normal.. an animal is just as if not more prone to biting out of FEAR than aggression.. in MY experience!
Plain and simple.. cat's DON'T hunt things sitting still for fun.. they hunt things they can chase.. YES this cat would have eaten your bird, were it not interrupted and was NOT doing this for game. A well fed feral cat that hunts for game is NOT going to hunt a still target that would be pointless.. not any fun, not honing a skill.. so IMHO.. the cat was indeed hungry.. and I'm sorry that the threat was understated! Apparently, despite it not often being an issue.. these things DO happen.. thank you for sharing, so we can start to realize that and maybe even consider and share it when needed!
Now why were there 3 of them injured is another question.. tries and fails, confused animal about which is the best target, someone else was on seen and the cat was left holding the evidence bag
Yes, it's hard for me too to image a place where only feral cats are the top predator.. Many things love chicken.. skunk, rats, domestic dog.. you name it.. I think like cat island is that in Japan?
Hunting rats and even gophers takes skill.. my dog's been bit inside her mouth a few times.. this is why domesticated TAME cats are often not adept rodent hunters and go after lots of birds or mice at best but not rats.
I'm more likely to believe that you haven't
seen any of the mentioned predator than you don't have any of them. BUT.. I am here to learn and find something new every day! I have not seen the majority of predators that I KNOW exist in my area.
Please.. do consider better security since clearly you do have this unexpected problem if you wish to continue keeping birds safely. Knowing your location would help make appropriate suggestions!
Did you need help caring for your injured birds? Or have you started another thread about it if you do?
