Mine are my shadow...lol They follow me everywhere I go!!! They are even in the bathroom with me while I take a shower.
My babies could be sleeping on the couch and the minute they see me get up they jump and start following me. The other day I was laying on the couch with them and I went to move just to get comfortable and Timmy jumped from the couch thinking I was going to get up...lol He did it 3 times...lol and they will not go in my bedroom with daddy to sleep unless I am in there.
Sorry I'm no help but I didn't have to teach them to follow me around the house. It came naturally.
