Woken in the middle of the night by strange sort of strangled yowling noises coming from the floor. Bear in mind that it took months before I had any vocalisations from either cat and both are incredibly quiet when they do "talk", so I feared the worst.
Sat bolt upright in a panic & turned the light on, only to see Boycat on the floor crouched over a disemboweled toy mouse, tail lashing and a wild look in his eyes. I was so proud of him for showing normal cat behaviour, but at the same time wished he'd chosen a different time & place. I should point out that he hadn't disemboweled the mouse then, the sad saggy remains have been in that state for ages since Girlcat decided to remove the catnip contents.
