How to check if the cat’s weight is normal

1.Observe the cat’s body shape

The body shape of a cat with short hair can be seen by the naked eye. If the cat’s pelvic bones and ribs can be clearly seen, and the belly has obvious depressions, it means that the cat is very thin. If the belly has a slight depression, then the cat is thinner at this time. If the cat’s belly is prominent, and you can see from the top of the cat that the cat’s body is narrow on both sides and wide in the middle, then the cat is already overweight.
The body of a normal-weight cat is seen from the top, the body is symmetrical, and the belly will not have obvious protrusion or depression from the side.

2.Touch the cat’s ribs and pelvis with your hands

If the cat’s hair is relatively long, it is difficult to observe the cat’s body shape with the naked eye. At this time, we can gently touch the cat’s pelvis and ribs. If the cat’s pelvis and ribs feel thick to the touch, but can easily feel the outline of the skeleton, then the cat’s weight is considered normal.


Weighing can accurately know whether the cat is overweight. If the cat’s body shape looks normal, but the weight exceeds the standard value, it does not matter. This may be because the cat likes sports very much and has more muscles.

Disadvantages of obese cats

If cats are overweight and look obese, you have to pay special attention, because obesity can cause cats to get diabetes, high blood pressure, organ diseases and other related diseases, and it will put more stress on the cat’s skeleton.

What should I do if the cat’s weight is abnormal?

1.The cat is overweight


  1. Breathing faster than normal cats

  2. Bad eating habits, such as eating too much at once
  3. After sterilization, energy consumption suddenly decreases
  4. The cat is very lazy and does not like to exercise or interact
  5. The body’s metabolism slows down with age


  1. Replace cat food with weight management prescription food
  2. Guide the cat to exercise more
  3. Feed regularly and reduce the amount of feed

  1. The body is thin and the skeleton is visible to the naked eye
  2. Drowsy and grumpy
  3. The amount of cat’s eat and drink become less


  1. Picky eat
  2. Body diseases cause cats to refuse to eat

Diseases like acute renal failure can make the cat very uncomfortable and make its mental state poor. Acute renal failure can cause cats to have symptoms such as refusal to eat, diarrhea, vomiting, and dehydration, which will eventually lead to the cat’s weight loss rapidly.


You should send the cat to the hospital for diagnosis in time. If the cat is dehydrated, also should give it an intravenous injection to help it rehydrate. In short, early detection and early treatment will have a higher cure rate.
