Patron Saint of Cats

626 AD-March 17, 659AD

By Rev. Brenda Griffin Warren

St. Gertrude of Nivelles is best known as the Patron saint of cats. Now, that intrigues me as I love animals of all kinds, yet I  have two cats who share their life with me or should I say they let me serve them. Yet, interestingly, no one knows why Gertrude is the Patron Saint of Cats, as there is nothing written about her with felines. The only guess for this designation is that there are some medieval depictions of her surrounded by mice. It was not even until the 1980’s that St. Gertrude became the Patron saint of cats.

So, let’s take a look at what we know about this saint who is not as well-known as some other female saints. St. Gertrude of Nivelles was born into aristocracy in Belgium in about 626AD. She was the daughter of Pepin of Landen, the mayor of the Austrasia palace (whose descendants through his daughter Begga’s marriage to Ansegisel later became the founders of the Carolingian Empire) and his wife Itta of Metz.  There must have been strong-willed genes in that family as Gertrude herself was strong-minded from childhood.

One day when Gertrude was ten years old, King Dagobert I, King of Austrasia, king of all the Franks, and king of Neustria and Burgundy came to have dinner with her family. A young man who was the son of the Duke of Austrasia was at a dinner party with the family. He asked the King to grant him Gertrude’s hand in marriage. When Pepin asked his daughter if she agreed to this engagement, she angrily rejected the proposal and with an oath said that she would neither have him nor any other earthly spouse, only Christ. Yes, she was only ten!

As Gertrude grew older, she and her Mother Itta set up an Irish- inspired monastery in the ancient Sonian Forest at Nivelles. It is said that it was filled with treasured handwritten books.  Itta was the first Abbess and then Gertrude followed in her footsteps. This Mother and daughter became good friends with the famous Irish missionary St. Fursey and his brothers Foillan and Ultan who first served in East Anglia  in southeastern England and then in France.

Gertrude soon began to assign her abbess tasks to others so that she could spend more time in spiritual tasks such as in prayer, in reading, and in scholarly study. She began to build and to support numerous churches that she dedicated to the saints and she ministered to orphans, widows, captives, and pilgrims.

When Gertrude became fatigued and ill at age 33 in 659 AD from extensive caring for others, she appointed her niece Wulftrude (the daughter of her brother Grimoald I) as Abbess. That same year, Gertrude asked a pilgrim (likely Ultan) from Fosses Monastery when she would die and he prophesied that she would die the very next day on March 17, 659 on Irish St. Patrick’s feast day. He also said that Patrick along with the angels would greet her and just as he prophesied she did die on St. Patrick’s feast day.

Gertrude left instructions on how she wanted her nuns to bury her in an old veil that a pilgrim nun had left at Nivelles along with a scratchy hair shirt. Her vita says that at her death there was a most pleasant odor,” a s if a burning mixture of scents, and it perfumed that little cell where the holy body lay. And we, having gone out from there, still sensed the sweetness of that wonderful scent in our nostrils.”

Her *vita beautifully describes this good Abbess:

“Gertrude did not cease to speak in constant praying and in preaching the word of God to her people. Rejoicing in hope, bearing up in tribulation, devoted in her heart, and calm in her appearance, she longed for her last day to be present,  the day of her heavenly journey.”

It was recorded that even after Gertrude’s short life of 33 years on earth, that she continued her charisma of caring for the suffering of others from the other side of the thin veil. Gertrude’s compassionate care from the heavenlies included saving lives at sea; stopping a fire in a monastery; curing a girl of her blindness; helping a young boy escape kidnappers; rescuing a man in chains; and resuscitating a servant boy  along with many other good works.

And Jesus said, “when you have done it to the least of these, you have done it to Me.”  Well done, good and faithful servant St. Gertrude of Nivelles.

Thank you for a thorough overview of St. Gertrude’s life. Most of us know her only as the patron saint of cats and gardeners. I did a post on St. Gertrude just today on my cat Buddy Foster’s blog. it’s good to know more about the real person.
