Humans like cats that communicate and do tricks. Here are some tips:
1) Meow at your food bowl. In takes a few tries on this one as they tend not to hear you. Try meowing in a loud meow repeatedly.
Tip: if one human has feed you when the other is not around you can try to get the other human to feed you as well.
2)Sit when they ask you to sit. Then stare at them sadly until they give you a treat.
3) Meow continually when there alarm goes off. This helps them wake up faster. After they awake lead them to your food bowl. They sometimes don't understand.
