It's generally not recommended to spay a mother cat one month after giving birth. It's best to wait for at least two months before considering a spay surgery.
Spaying a mother cat one month postpartum is not advisable. Ideally, wait for two months or more before scheduling the procedure. After giving birth, a cat's immune system is typically weaker. Allowing two months provides adequate time for her body to recover to a normal state. It's crucial to ensure the cat is fully recovered before undergoing surgery, and a pre-surgery health check is strongly advised.
If the mother cat hasn't weaned her kittens naturally, plan for weaning around two months post-birth. This allows the kittens to gradually transition to solid food. Once the kittens are fully transitioned to cat food, then the mother cat can be scheduled for spaying.
Kittens usually need around six weeks to properly wean. Therefore, to ensure sufficient milk supply for the kittens, it's wise to wait until after they are weaned before considering spaying the mother cat.
Also, it is vital to avoid spaying during the mother cat's heat cycle (estrus). During this period, her uterus will be engorged with blood, increasing the risk of significant bleeding during surgery.
