The survival rate for a first-time mother cat's kittens is generally around 80%, and there's absolutely no reason why they shouldn't be kept. Regardless of whether it's the first or a subsequent litter, as long as the mother cat produces sufficient milk, the kittens can thrive and grow healthily.

Nutritional Needs During Pregnancy
During pregnancy, a mother cat requires ample nutrition. In the last half of her pregnancy, it’s essential to supplement her diet with calcium to ensure the proper development of the kittens' skeletons. Typically, a cat can give birth to a litter of four to six kittens. If it's her first litter, the number may be smaller, around one to three kittens. With fewer kittens, the mother’s milk is often abundant, leading to each kitten being well-nourished, resulting in a high survival rate of approximately 80%. These kittens often have robust health and strong constitutions.
Factors Affecting Kitten Survival
A kitten's survival rate is not primarily determined by whether the mother is giving birth for the first time. Instead, it is more closely linked to the kitten’s inherent health and development. Larger litters can result in kittens of varying sizes, with smaller kittens potentially suffering from congenital health issues. To ensure that kittens thrive, owners need to provide proper prenatal care for the mother, prevent her from falling ill, and ensure the newborns are kept warm after birth. First-time mothers might need extra supervision to ensure they do not accidentally crush their kittens.
Debunking the Myth
In the past, particularly among older generations, pets were often kept primarily for pest control or guarding. There was often less emphasis on proper animal care, leading to higher mortality rates for first-time litters. This contributed to the misconception that the first litter is less likely to survive. However, the real reason for this is that cats enter their first heat cycle around six to seven months, while their bodies are not yet fully mature for reproduction. Mating at this young age can lead to deformed or weak kittens, increasing their risk of death. Furthermore, younger mothers may lack the maternal instincts to properly care for their young, with some even consuming their kittens. Kittens born to cats over one year old are typically healthier.
Modern Cat Care Practices
With today's improved understanding of cat care, proper nutrition and vet care have become commonplace. Therefore, there is no valid reason to assume that a first-time mother's litter is less likely to thrive. Providing appropriate nutrition, a clean and comfortable environment, and prompt veterinary attention can ensure all kittens have a fair chance at a healthy and happy life. Focus on supporting the mother cat's health and following recommended kitten care guidelines and you'll be able to see your kittens thrive. The key to success is preparedness and attentive nurturing, not abandoning an innocent litter.
