A cat's degree of body laxity often depends on the individual's personality and environment. Some cats may be more relaxed and comfortable and therefore appear more relaxed around them. Other factors include age, health, reproductive status and individual differences. For example, older cats may be more lax because they may no longer have to defend themselves or find food.
At the same time, if a cat feels safe and comfortable, he may also be more relaxed. If your cat appears to be particularly flabby and you are concerned about his health, it is recommended that you consult your veterinarian. They can help you understand your cat's health and determine if further treatment is needed.
