We've had the pleasure of caring for Jack for over two years now, and he still manages to surprise us.
For instance, we woke up in the middle of the night to a strange rustling noise. When we turned out the light, we found Jack had settled quite comfortably in this dresser drawer. Surprisingly he both got up into the drawer (2nd from bottom), and managed to fit inside of it.

Secondly, despite being emasculated years ago, and being a fairly... let's say "leisurely" cat, Jack is still inclined to defend his honour and his territory. When a rogue element was discovered in our yard yesterday, this is the scene the ensued:

We broke up the fight when it got dirty, and Jack was not injured in the melee. But I have a feeling we haven't seen the last of Lord Blacky yet.
On Saturday, we took Jack to the vet to get his annual shots, and of course we got him weighed. He's now in his teens, weighing in at 19.8 lbs! Yay Jack! At this rate he is soon to be featured on the cover of FQ.
