Apes do not have mobile ears or a tail, this makes communication difficult as they do not always understand what you are telling them. You have to make a sound to get their attention. Now not wanting to feel like a constant nag hissing is not really my first option. Anyway I tried and it just picked me up and moved me! oh the shame the indignity especially as I was just a kitten at the time. So no hissing unless they really need telling off, a cry repeated usually works.
If it is their attention you require, and lets face it our apes often appear to just take us for granted. tapping them with your paw is quite effective. Best to keep your claws in for this. Another handicap these poor fools have is their lack of a natural fur coat and they object to your claws coming directly into contact with their skin. Again there are times when it is necessary to discipline your underlings and of course you claws are very useful for this a quick swipe soon put them right.
When you are hungry, or just fancy a little nibble, you must use everything you know to get them to remember their duties. Yet another weakness on their part they can be slow to understand that we felines want what we want when we want it and no waiting around. Almost constant crying, paw tapping and wrapping yourself around their legs are all useful approaches to take. Being creatures of habit we are fully entitled to expect them to follow those habits in their service of us.
As you can tell by the picture, yes that gorgeous creature is me, another way of making your wishes know when it comes to food is to sit beside your empty or near empty food bowl, This tactic also serves to remind your companion felines that this is your bowl and the food in it is yours.
All in all our bold apes require a lot of effect to communicate with, but once you get the knack of it the rewards are worth it. Now if you will excuse me I have to go and get mine motivated.
