Why Do Cats Gain Weight After Spaying. Spaying or neutering is the best way to control pet populations and help prevent various diseases. In my opinion one of the biggest downsides of spayneuter is an increase in the incidence of weight gain.
The loss of estrogens and androgens sex hormones from neutering dogs and cats causes a decrease in metabolic rate thus their energy needs are lower. Obviously there is a change in hormones after the procedure. So the fix is probably as simple as giving Missy a little less food than before.
An increase in food intake appears to be the most significant contributor.
This can be prevented and controlled. The benefits of neutering and neutering our feline friends are endless from controlling the cat population to reducing the risk of behavior problems. Neutering a pet is linked to an increased risk of unhealthy weight gain and obesity if there is no change in diet or feeding plan at the time of surgery. So the answer is yes spayed and neutered cats do put on weight but the experts are unsure why.
