Why do cats gain weight after sterilization? - briefly
Cats often gain weight after sterilization due to hormonal changes that reduce their metabolic rate and increase their appetite. Additionally, their activity levels may decrease, contributing to weight gain.
Why do cats gain weight after sterilization? - in detail
Cats often gain weight after sterilization due to a combination of physiological and behavioral changes that occur following the procedure. Sterilization, which involves the removal of reproductive organs, significantly alters a cat's hormonal balance. In females, the removal of the ovaries reduces the production of estrogen, while in males, the removal of the testes decreases testosterone levels. These hormonal changes directly impact metabolism, often slowing it down, which means the cat burns fewer calories at rest than before the procedure. Additionally, the reduction in sex hormones can lead to an increased appetite, as these hormones play a role in regulating hunger signals. This combination of a slower metabolism and heightened appetite creates a higher likelihood of calorie surplus, leading to weight gain.
Behavioral changes also contribute to post-sterilization weight gain. Neutered cats tend to be less active than their intact counterparts. The decrease in roaming, territorial marking, and mating behaviors reduces their overall energy expenditure. Without the drive to seek out mates or defend territory, cats may spend more time resting or sleeping, further lowering their calorie burn. Owners may also inadvertently contribute to weight gain by overfeeding or providing high-calorie treats, often without realizing that their cat's energy needs have decreased after sterilization.
To manage weight post-sterilization, it is essential to adjust the cat's diet and encourage physical activity. Portion control, feeding a balanced diet specifically formulated for sterilized cats, and engaging in interactive play can help maintain a healthy weight. Regular monitoring and veterinary consultations are crucial to ensure the cat's overall well-being and to address any weight-related concerns promptly.
