The ultimate message I want to convey to a 4-5 month old cat is that he is free to run and jump and attack his toys and be as crazy as he pleases in the majority of the house. However, if he chooses to come on the couch or on the bed, he must remain relatively quiet and still. When it is play time, he must remain off of the "calm zones."
As an example, my habit is to read in bed for about a half hour before turning off the lamp and going to sleep. As I was doing so the other night, he came up, wondered around, the began to bite my knee through the blankets. He quickly got picked up and placed on the floor. He soon was back, and this time he grabbed on to the corner of the blanket and started to claw and chew at it like a toy. Again, he was quickly sent to the floor. Finally, he came back a minute later, and laid down against my arm. Now, he got some petting and soft talk. He stayed that way until after I feel asleep.
So it seems he might be starting to learn, but I want to be sure. I know there are dozens of related questions here, and I will read them, but none seem to cover this exact scenario.
