Weight loss in cats

When we have an overweight animal at home, it is always easier to put it on a diet, since it will eat what we give it but, ¿What happens if you eat the same old thing and lose weight? Here we have a problem. If in a short period of time you lose 10% of your weight, we may be facing a serious problem.

Weight loss is not a disorder in itself but it can be an indicator of another disease that our animal is suffering. In any case, the cat can not only lose weight due to illness, it can also do so due to psychological stress or changes in diet. We will detail below the possible causes of your weight loss.

Simple causes

We'll start with the simplest thing that we sometimes overlook. We can have a cat very energetic and that it is very difficult for him to settle for what we give him to eat. He tends to roll over and not eat, so sometimes we opt for less nutritious meals and lose weight. They are cats that play a lot, jump, run and sleep little. In these cases, we should increase the servings or choose a more nutritious food for them and see if they still do not gain weight or, on the contrary, they begin to regain their ideal weight.

The psychological stress it is usually one of the main causes that explains why your cat eats well but is very thin. It can be due to changes in the habitat such as moving, abandonment of a member of the household family, whether animal or human, many hours of solitude or, on the contrary, too much activity in a house where there was none. This happens a lot in grandparents' homes who spend time with their grandchildren and the cats are forced to have an extra activity that they did not have before. There may be depression due to the death of an owner and / or partner or, new members in the family.

The changes in diet They are usually another of the reasons that cause weight loss in the feline. We must bear in mind that although we do not see diarrhea and / or vomiting, they may be going through internal changes due to the new food. It happens a lot when we switch from commercial feed to homemade food. Habits tend to change, since in homemade food we force them to eat when we put the plate and we do not leave it there throughout the day so that they eat when they are hungry, as happens with dry feed..

Diseases that can cause the cat to be very thin

In general, when disease-related weight loss occurs, other symptoms are common. There may be dull or hair loss, vomiting, diarrhea, loss of appetite, increased thirst, etc. It is very important to talk to the vet about this and comment on everything observed, since it will be necessary to look for the cause that is triggering these symptoms.

Although there are several pathologies that can cause the cat to eat well but be very thin, the most common are usually the following endocrine diseases:

  • Mellitus diabetes
  • Hyperthyroidism

Both are usually associated with cats over 6 years old..

In addition to the above conditions, there may also be digestive problems from the mouth, such as the lack of teeth, infections in teeth or gums, etc., to the entire digestive tract, such as stomach ulcers, inflammations, stomach or intestinal gas. There may also be presence of tumors that still show no other symptom than the loss of body weight. Likewise, there may be a beginning of renal failure, that if we are not attentive it can lead to chronic kidney failure with all that this disease brings over the years.

Diagnosis and treatments

When we detect that our cat loses weight we must go to the vet to take the corresponding exams. We must tell him the possible simple causes that fit our feline so that in the medical history he considers them and determines the best treatment to follow.

The vet will most likely perform a blood test and, perhaps, a urine test to make the diagnosis, and rule out or confirm the presence of the aforementioned diseases. If finally the cause that explains why the cat eats well but is very thin is a disease, the specialist will be in charge of stipulating the best treatment to combat it..
