Hic non defectus est, sed cattus minxit desuper nocte quadam. Confundatur pessimus cattus qui minxit super librum ostum in nocte Daventrie, et consimiliter omnes alii propter illum. Et cavendum valde ne permittantur libri aperti per noctem uni cattie venire possunt.
Here is nothing missing, but a cat urinated on this during a certain night. Cursed be the pesty cat that urinated over this book during the night in Deventer and because of it many others [other cats] too. And beware well not to leave open books at night where cats can come.
Waste not, want not! Our intrepid writer is not about to start over again. What he does do is leave this handy advice to the lucky owner a book peed on by a cat in the night. I love history.

Here is another link that I just discovered detailing this image above and few more humorous markings of cats immortalizing themselves on print!
