Athough i don't Agree with her act... i might get stung for this reply, but if shes local, its not uncommon for people to constantly see others cant digging up your flower beds and taking a dump on your lawn, heavens knows how many times i have had it done to me in the past or i hear my father daily moaning about it even with the amount of humane devices he has setup to deter this, could be a simple act of ' I've had enough with this cat pooping on my lawn first chance i get, when i see this cat its gonna get it' and bingo opportunity arises and it ends in the bin.
Although the act wasn't nice it wasn't exactly cruel to an extent that i have seen other animals mistreated. How many programs have you seen that show cats and dogs locked up in confinement, kicked, beaten, not fed, flee infested?.
But i think most will agree Cats in general are a nuisance we all put up with. i have to admit that i really dislike cats, ever since one got through our kitchen window and killed my wife heard of guinea pigs ( i tell you she was upset about them being killed by a cat for a good while, took me hours to clean up the body parts of 4 pigs and had to redecorate the dining room to remove the last of the blood stains) animals are like your kids and loosing them to another animals act due is not pleasant.
Athough this is animal behaviour, you tend to find that dogs are far more loyal and obedient than a cat ever will be, this is no excuse to treat any animal in such a way but it does give some reason to why animals can be treated badly at times.
Currently at the moment we have 2 baby guinea pigs and a Jack Rustle who's 6 months old as most will know jack rustles are rat dogs and will happily kill any rodents but yet he has never touched our pigs due to the fact he is trained to ignore them. but in regards to cats most train them to be litter trained or just let out and the owners should take responsibility for cat poo same as we have to take responsibility to pick up your dog's mess or be fined. Should cat owners be fined up to £2000 for there mess same as a dog owner? I firmly believe they should. why should others have to do the work of there owners?
I tell of a story i had about 5 years ago when a next doors neighbours dog used to jump over our fence and take a dump in our lawn regally i could never manage to get to the dog to throw it back over the fence after many many arguments with the neighbour about it & phoning th police on several occasions ( there rubbish little chats' waste of my time to be honest) in the end i solved the issue over a period of a week, every time the dog jumped over and took a dump i picked it up and posted it through her letter box after a week of this i never saw the dog come over again!
Back to the point:-
Admittedly this is speculation of whats gone on, the papers don't tell the past and its all just one video showing an act with out reason but until we know the reason for her behaviour we can only speculate on what a bad person she is, But if it was a pure act of cruelty in which case should be followed though with a punishment fitting the act.
feel free to post your oppinion on my own I'm happy to accept grief about it but this is my oppinion that I'm voicing but please don't think I'm standing up for her behaviour or condoning it as i have never treated an animal in such a way just be open minded about whats triggered her actions if any.
