Thomas was known as Thomas T. Bombadil, aka Most Puissant Rat Slayer. Here are the words from Thomas on the Paws and Effect blog.
“I adopted Mama on March 17, 2004. I was 3 years old at the time and had just gone through a series of fairly traumatic events. I was feeling quite poorly and not even sure if I wanted to stay in my body anymore, when Mama came along and visited me at the shelter where I was living. For some reason she fell in love with me, even though I was so sick and sad and covered with snot, and as soon as I got well enough to find a forever home, Mama and Sinéad and Siouxsie welcomed me into their lives. I earned the title Most Puissant Rat Slayer when I was living on the family farm with Mama, and I singlehandedly got rid of all the vermin in the barn!”
