I think it’s important that you do this, and often, because how else could the cat know its own history, and pass it along to future generations? Oral histories are key for cat historians, and so few people disseminate such vital information to the cat population, who as a result enroll in Cat History programs (Ph. D. or MA) far too rarely. Don’t listen to those nutjobs btw who will tell you that you’re acting like a lunatic for sharing conversational subjects you indulge yourself in with household pets–any sensible person understands that cats do benefit greatly from hearing your discourse on certain specific subjects, just as human children learn from being spoken to. The cat is IN NO WAY a poor substitute for a child, and you should never listen to (or even tolerate) some unkind person suggesting otherwise. Onward and upward!
