As I type I am eating my dinner. There is a cat staring at me (and the food) to my left and to my right another is sneaking along the desk towards my plate. It is a joint attack.
In the kitchen is two bowls of cat food that have just been put out.
As soon as they are sure that they are getting none of my food - once I have eaten it all - they will go and eat their food.
At least with a dog you can admonish it and send it into the next room. A cat will laugh at you if you try that.
Have fun! :-)
