Boycat is strongly hinting that I'm not catering to his needs as a macho prime predator.
Last couple of days, he's dug up an old knackered mouse toy - by knackered I mean there's just the fur covering left & the former contents have been removed. He's been throwing it around, killing it then parading round with it dangling from his mouth in exactly the way he did with real mice when I had an invasion in the conservatory & let the cats loose in there.
Clearly I need to invite some mice to move in, so he can hunt, play with & kill them!
