LOL LOL Good question. Honestly, I think cats are smarter then they let us believe I do believe both Marius and Scooter listen to everything we say and can understand most of it..but they don't always necessarily heed what we say! LOL LOL

They both know their names and of course the word "NO!"...although this is only selective hearing

They know "food!" "Treat!" "sit pretty" "down" "out" "come to momma" "sit on momma's lap" "good kitty" and who knows what else they really know...

LOL LOL
