Dad is Cat and Dog's long-lost adopted Father, who appears in "CatDog and the Great Parent Mystery" and "Vexed of Kin”. He is very laid back; he also tends to be more grumpy such as Cat is. Dad does love his boys and loves to have fun with them and his wife, Mom. Dad is a little green frog. He likes to burrow in Mom’s fur making Mom have four eyes. When CatDog were babies, Dad would rock them to sleep on his nose. He is not often openly loving, but he does have a soft side. He loves his wife and his boys.
