In 2003, Straczynski rescued a Maine Coon (a breed of cat) kitten that had fallen into a landscaping drain in his yard; a 16-hour operation which ultimately involved digging up large portions of the yard and calling out the fire department and a number of plumbers.

Has a degree in clinical psychology and one in sociology.

During season four of Babylon 5 he would frequently dunk his hands in ice water, because they were so sore from writing.

Once spotted a young man dressed as a Narn at a science fiction convention. Straczynski was so impressed at the craftsmanship of the costume that he remarked, "You came out of my head, but I know for a fact that you don't work for me.".
