My cat and I have a ritual when she gets fed or gets a treat. She asks me for her treat, (vocalizing or coming to get me) and then when I open the cupboard door, she gets up on her hind legs and gives me a kiss, (we bump noses). Then I tell her to sit, and she does, while I get her treat out for her. She waits in her sitting position until I put the food in her bowl. We have been doing this for a while, so now I don’t even have to give her the sit command, she just does it on her own.
