Why are cats maniacal with food and dogs less?

In Science Daily Online we like to inquire about the customs and curiosities of our favorite pets: dogs and cats .We already talked about why dogs obey and cats do not and on this occasion we want to investigate about a behavior that you will surely have observed in dogs and felines.

The first usually throw themselves and devour any food that falls at their feet, instead cats don't .They sniff, approach, seem fearful, study food and, on many occasions, turn around and leave it. Why this difference in behavior?

Scientists respond

Cats' behavior towards food is often labeled "capricious" or "gourmet." The dog, on the other hand, seems to have practically no e brake at the time of feeding.Extranaados, the scientists of the Monell Chemical Senses Center of Philadelphia, believe to have found an explanation .

Why are cats maniacal with food and dogs less?

The cat rejects food because it detects in them some bitter substance .The cat , surprisingly, has 12 genes to detect the bitter taste o.This makes them despise many foods.The dog on the contrary is much less sensitive to what bitter and eat a greater number of foods without stopping to analyze them.

The genes that detect the bitter taste

The herbivores have a group of genes that serve to detect the bitter taste of the herbs that they eat.Usually, the bitterness that detects the sense of taste, warns them that what they are going to eat can be toxic or bad for your health.What the scientists saw is that the cat , which is a carnivorous animal, has not lost those genes .In most carnivorous species these genes have been reduced, since that plants are not their usual food, but not in them.

Why are cats maniacal with food and dogs less?

First it was thought that this could have happened because of the type of animal they hunt . Frogs and Toads, For example, they may have in their skin some toxic that would poison the cat.This hypothesis is ruled out since there are few occasions in which they hunt this kind of animals and this would not justify the conservation of the genes .

Secondly, they looked at humans. men we have bitter receptors in addition to the by mouth, in the heart and in the lungs. It is believed that this is to detect infections.Perhaps cats also serve them for this purpose.

Scientists will continue investigating to find the ultimate cause of cats' behavior towards food.At the moment they firmly believe that is due to the conservation of those 12 genes that serve to detect the bitter taste .
