I've noticed lately that during their boisterous wrestling matches (which Tiny enjoys a lot more than Simba) Tiny seems obsessed with trying to gently bite Simba's neck, causing Simba a good deal of consternation. Is this because it's how mother cats carry their kittens? Is Tiny asserting his dominance over his long-suffering little grey buddy by doing this? While watching him doing it, I always imagine Tiny saying, "ha! See that? I'm your mum! I'M your MUM!" Do anybody else's cats do this?
