I found this recently in my mother's papers. (Yes, I am STILL going through her stuff, almost a year later!) Mac (k) was our extra large black cat, known for his shenanigans on the campus at MacDuffie, the boarding school where my Mom worked and where I was a student. This was likely written by one of the security guards; they have a little office at the campus gates and would have seen the drama occur.

 I couln't get the text to read more clearly:

"YOUR CAT MACK CAUGHT A BABY BLUE JAY (ONE OF TWO THAT FELL OUT OF THE TREE IN THE TRAFFIC CIRCLE IN FRONT OF RUTENBER HALL), MUCH TO THE CHAGRIN OF THE PARENT BIRD, WHO PURSUED IN A LOW-ALTITUDE ATTACK DURING MACK'S HASTY RETREAT, QUARRY CLUTCHED IN HIS JAWS. THE PARENT BIRD CONTINUED TO HARASS AND VERBALLY CHASTISE MACK AS HE PLAYED WITH HIS CATCH IN THE DRIVEWAY NEAR YOUR CAR. NO DOUBT YOU WERE WAKEN BY THIS VOCAL ASSAULT. PARENT BLUEJAY ASSEMBLED OTHERS INTO A CHORUS OF ORAL ABUSE, TO NO AVAIL." 

This brings me such laughter and joy - the whole scenario, and the fact that my mother kept the note for, um, 20 odd years?

I hope this makes you smile.
