JanRN, Sammys legs are too short for him to jump, he just stands in front of the sofa staring at it and if you don't take notice of him he gives you a low growl and like the dutiful servant you are, you pick him up and put him up on the sofa, where he can stay for hours. When he wants to get down you just hear a little bark, like he is saying come here and you go and lift him off.
I know I know talk about being spoilt rotten
