I have the sweetest cats that ever lived.
Sushi, the 4 month old, eats a teaspoon of liquid food every morning. Spice, the year-and-a-half-old, does not.  But every morning Spice comes in  meowing, drags me to the fridge and literally pushes me until I put a teaspoon of cat food in the bowl.  Then Spice calmly walks away so Sushi can eat it.  Heck Sushi even stopped asking for it since she knows Spice will do it for her.
