I think this is a Yamaha FZR 400. The exhaust pipe is tripping me out at it looks a lot like a two stroke pipe, but might be the darkened details blending in with the lower half of the engine. All FZRs from 1987 to 1996 (or 1999 here in the US) were four-stroke engines.
>The length of pregnancy in the rabbit is 31 days and the doe can produce from 1 to 12 young each time she gives birth. She can become pregnant again within a few days of giving birth. However it is not good practice to allow the doe to become pregnant straight after giving birth. It is better to mate the doe when her young (litter) are 4 weeks old so that they are 8 weeks old when the next litter is born. In this way one doe can produce 6 litters a year.
Given she looks about to give birth any moment and is only now bringing it up definitely supports the 31 days part.
I can't help but see skull enema and I wonder how that works.
Well, seeing as a human rectum can stretch far enough to accomodate at least one racoon, it'll probably be something a lot like that. Though with a whole lot less fur and angry wiggling.
