Rhubarb Returns

Greetings Sportsfans!
I just wanted to post a review on a terrific movie our family viewed(for the first time) last night. What a riot!! We were quite caught up in the fast-paced action and suspense! The amount of trivia on this movie seems to be a bit limited. I originally came across the name Rhubarb while looking up credits/details about the cat called "Neutron" on This Island Earth, and later Orangey from Breakfast at Tiffiany's. Extensive trivia on animal actors pre 1966 seems to be quite lacking. Does anyone know of a text reference for all those great creatures? Until then ...meow
