mine understand: - whiskas -dreamies -bedtime -cuddle ( said while making a patting noise) -dog -give me your paw They go to different places and make different actions for all of these. If i say the wrong word in the wrong place, they don't always notice, but sometimes they do. If I am standing by the feeding bowls where I give them Whiskas in the kitchen, and say "dreamies" they move off to the "cat entertainment area" in the hall, where I hide treats in their toys. If I say "bedtime" though they just look at me like I'm an idiot. Maybe they only understand the word "bedtime" at night, I should try saying something that sounds similar instead, like "paper" and see if they still shoot upstairs and stand by my toothbrush waiting for me. I don't know if they know their own names, though, as they all come if any one of them is called. It might be that the other two are thinking " I'll go and see why they are being called and I am not"
