Hi Ashley,
So sorry to hear about your Anna. Hope she gets better soon.
You know, your story of your neighbour accusing your cat of defecating in front of her home is the same experience I had recently.
A neighbour on the same floor approached my mum the other morning while she was babysitting Blackie at the corridor....we let him out twice a day, but would keep him company and never leave him alone even for one minute.
She pointed at Blackie, and asked my mum "is this your cat". My mum said yes, and she immediately said our cat went to her home and defecated at her doorstep.
My mum was non-plussed, as Blackie would always rush back in if he needs to use the toilet...even if he's sleeping on our bed, he'll get up and rush to his litter box. Second, Blackie is never out of our sight...so how could he defecate outside her door?! What is she talking about? My mum wondered if perhaps this neighbour is trying to make a few complaints, and then, later, head down to the management office and lodge an official complaint. Pets are not allowed in condos, you see, and while there are those who keep dogs, there are also those who hate cats for some reason.
Just like some of the forum members here said, there are people who pour HOT water on cats. In my old place, there were many stray cats. The management scolded me for feeding the cats. They have their kitchen staff pour hot water on those cats if the cats went near their kitchen.
We wondered why the number of cats kept declining, or that we'd see their carcasses a few days later. We didn't know what had happened and only found out much later that they were killing the cats by pouring a big pot of PIPING HOT water on them!
But like Lupie says, what goes around comes around. The management has since gone bankrupt and the OA has wound up their office. But, unfortunately, the big bosses (you'll be shocked if you knew who they were...very famous VIP) carted away all their precious assets before the OA closed their office.
