These are collectors cards we fanmade as a gift for the visitors of Red Dwarf at Trpaslicon
Kryten is called Kryton in Czech Republic, for pronunciation reasons and better inflection. And also because, in Czech there is a word “kretén” which means “asshole” 😀
Cat is called “Kocour” which is the generic name for a male cat. All cats as a species are called “Kočka”, but the male is called “Kocour” and the female is called “Kočka” :). So yes, “Kocour” is name of the Cat in Czech translation.
