Alas he’s gone our little friendly rat,
we’ll miss that trusting paw, those gentle ways,
as snuggling close to us content he sat.
Where now that little eager furry face,
those twitching whiskers, beady eyes? Such grace!
Poor Jack, you should have lived as long again
had you but had your rightful span of days.
You’ve left us now for where there is no pain,
which should console, but yet I must complain
to lose so soon this loving pet and friend.
The world may scoff and show its harsh disdain,
forget that we all share the self same end.
So Jack, we’ll say a very fond goodbye,
rememb’ring that at last we all must die.
