Re: If only we were allowed to kill these bloody vermin!
"If it is your cat, it is your responsibility. This is not some wild animal, such as a fox, that we're talking about. It's a non-native, domesticated pet that you've let loose in the neighbourhood."
Try looking at what the law says some time. Cats are known for their prowling wandering behaviour. To that end, if a dog is killed (accidentally) it must be reported to the police, and there can be consequences. If a cat is killed, tough shit on the owner. The possible consequences would relate to animal cruelty, however a clean shot to the head would likely not be considered "cruel".
This is why in rural places, hunters frequently pick off cats. They can always use the "it looked like a stoat" excuse, but it happens (even to a tabby with a bright yellow collar with bells on - some stoat), and people just have to deal with it. Right now, as it is a Sunday, the two outdoor cats are rounded up and locked in a stable, so they don't become targets.
If a hunter was to intentionally shoot one single dog, all hell would break loose.
Likewise, the person with the cola/vinegar squirter is being cruel to the cat, but as a cat owner myself, treatment of that nature is something we have to put up with in exchange for the fact that our cats won't stay put if they get the urge to go walking. Sometime they need to learn the places that are off limits, and given the attitude of the average cat, just saying "no kitty" isn't going to cut it. The cat will need to be inconvenienced. Then it might learn. If it feels like it. Maybe.
Yes, cats are definitely hackers. Sometimes I suspect they hack reality when we aren't looking.
