In our house It is not so much seeing as actions. My beloved Patchs I believe wrote the book. Mit's and Lucky have read it and added too it. Patch would make sure that I went to bed on time, now Mit's job. As with Patch once he thinks I'm asleep he move, untill then he has to snuggle next to my head using a soft purr. Both Mit's and Lucky have too keep an eye on me. Like Patch, Lucky leads me to the bath room. He will wait untill I have finnished my shower and I give him a hug. Then I tell him I'm going to get dressed. He will lead me to the stairs where Mit's takes over.
If I am not well Patch would sit on my chest so that I could not get out of bed. WELL Patch was 7 lb. Mit's is 16 and Lucky will be right behind him at 9 lb. If I try to get up thay will block me any way they can. They will snuggle untill I am feeling better. Lucky does not come on to the bed at any other time and Mits sleeps at the foot of the bed other times.
So Patch's is well represented in our house and I still miss her after almost 9 years.
