FELINE CONFUSION AND DEAD COOL GIFTS.
I think the cats are confused, one more so than the other. We've just got back from using a friend's cottage and their two pet cats were in residence instead of where they are usually at. One looked as if she was pining - mum - the other bigger one, her daughter, was constantly out killing things to bring us back gifts to put on our bed during the night.
Do you fancy having a half dead dragon fly or the heart of a rabbit, or maybe it was the stomach, laid on your pillow while you sleep? We saw the cat jump into the bathroom sink to lick the water. There was fresh water laid out by the the cats food bowls; there was one bowl of food and one bowl of water for each one.
Sure these pets are confused, the cottage guests work by different rules to those they have got used to. They hadn't got the run of the whole of the house nor the kitchen work surfaces, that was definitely OUT. We had bathroom and bedroom doors closed at night and during the day. Their food was regularly given and their water bowls refreshed. The cat flap was used readily by the hunter/killer, and only when the door was open and the weather was okay, her mum sauntered out to explore.
