Weight gain following neutering or spaying is completely avoidable. For at least six months following surgery, pay close attention to your cat’s eating habits and overall health.

Make sure you stick to a schedule by maintaining mealtimes at set times and filling the gaps with fun activities and new experiences.

There are many different cat toys available that will keep her entertained.

You can do the following things to prevent her from going back to this habit:

  • In order to account for the drop in energy requirements, change the amount of food provided. Consult your veterinarian before making any changes to your pet’s feeding schedule.
  • Forget about free-choice feeding and instead give your pet a set amount of food each day depending on their calorie requirements.
    As table scraps are frequently calorie-rich, avoid giving them to pets.

Frequently Asked Questions

Do cats eat slightly more after being spayed?

Sterilization entails the removal of sex organs that produce hormones. The elimination of some hormones generated by the sex organs, which play a part in appetite regulation, lowers the neutered person’s capacity to manage their appetite adequately.

The neutered cats are more likely to eat more food than the intact cats, despite the fact that the spayed female typically uses less energy than the intact female.

Unwanted weight gain is almost certain to occur when there is a decrease in energy demand and an increase in appetite. Due to the added stress that excess weight places on the body, obesity is a dangerous medical issue.

Diabetes, heart disease, joint damage, and a host of other health problems are all made more likely by obesity.

What is a feline’s post-operative diet?

With careful food management, it is more than possible to raise a sterile cat in perfect health. However, certain diets can help with the work at hand.

Age-specific diets are available for cats that have recently undergone spaying, ranging in age from 5 to 8 months to elderly spayed cats.
Reduced energy density, or fewer calories per serving, aids in maintaining a healthy body weight.

L-Carnitine and high-quality protein both contribute to reducing the accumulation of fat tissue and boosting lean muscle mass.

Complex fiber content guarantees that every serving satisfies the appetite.
