It is not enough to accustom a kitten as a child to eat a certain type of food, or several to ensure that he always eats them: in fact, an adult cat takes on specific tastes.
These can be limited and then change suddenly just as happens to those who are greedy for a dish and, after having indigestion, can no longer eat it.
There are some common places about cat feeding that should be kept in mind.
Do not be surprised if your cat does not eat any of it, in fact, like all other felines it is purely carnivorous, there are numerous elements in its diet that are still rich in fiber.
In any case, try to add vegetables, pasta or rice to the gruel, there are also commercially available flakes rich in fibrous substance, if once again your little friend is obstinate in being carnivorous, no problem, he will live very well anyway.
Like all mammals, milk is the main element in the first months of life, however many specimens that have become adults, no longer producing lactase (the enzyme dedicated to the splitting of lactose), are no longer able to digest it.
At this point there are cats that spontaneously reject it, other gluttons instead, who continue to drink it, causing intestinal problems such as aerophagia and dysentery.
Do not make the mistake of diluting milk with water at this point, it would be useless.
It is common in common thinking that cats are fond of fish. It is an excellent element and many domestic cats feed on it to refuse any other type of meat, however there are specimens that do not like it.
Given the low cost, the lung has often been used as a strategic food for "at home" meals, but, being a spongy tissue and poor in nourishment and, requiring a long cooking to avoid the presence of any parasites, it is always better to avoid it.
