I can tell when my cat is genuinely hungry by his weight

It sounds improbable but I can tell when my cat is genuinely hungry by his weight when I pick him up. I can feel the differences in his weight. I believe that cat caregivers need to fully understand when their cat is genuinely hungry and will eat the food that is put down before them as opposed to those times when domestic cats sometimes are seeking what I will call "food therapy". Too much wet cat food is wasted. Think how many millions of tons of cat food is waster annually.

My cat has a 'primordial pouch'! Not call domestic cats have them. As you can see he has a perfect body weight or BMI! That's because he is active and eats well.

  

Sometimes domestic cats eat out of boredom I believe or because it is just there and instinctively, they eat some of it. But I know my cat's weight or the feel of his weight by picking him up. And I can tell the difference between when he has lost some weight and when he has gained a little bit of weight. The difference is subtle.

When he feels light, I believe that if he is asking for food at those times, he is genuinely hungry and will eat the entire bowl of food that I put down for him. This has been proved true time and again.

If I'm correct, it is a useful check. I don't know about you but I feel that I waste too much cat food. I decide to give him food with care and with as near certainty as possible that he will eat it. However, sometimes he shows some interest but then leaves it. In that instance you have almost certainly thrown away an entire sachet of wet cat food. 

Perhaps cats vary in this aspect of their behavior. Perhaps some cats are more predictable. But then again perhaps some cats always eat their food and are obese as a consequence.

Sometimes, and I stress that this is quite rare, he does come back to wet food that has been left out for quite a long time and eats it. He does this because it smells stronger and domestic cats are scavengers unlike their wild forebears and so he might scavenge some hours-old wet cat food during the night.

I'm trying to figure out some scientific reason why there is a link between my cat being genuinely hungry and being lighter than normal. I think is because he has gone to the toilet and a few or more hours after going to the toilet his eating rhythms kick in and he is ready for food. That is a guess. Or he is simply more active at some times and eats later than normal. Under these circumstances he burns some fat and therefore feels lighter.

But I can quite definitely detect the difference in how much he weighs simply by picking him up. I can also combine this with palpitating his body. Sometimes he feels a little bit thinner than at other times. There's a natural weight fluctuation. I am sure that this is entirely normal and happens with humans.

Detecting his weight helps guide me as to whether he needs genuinely needs food or not.
