The Question
“Dear Dr. Paola,
My feral Momma Cat (who is not even a year old) has had her 5 babies, and I have
gotten her to let me pet her. She’s a perfect momma. But she has gotten so thin. What can I give her to gain some weight? I will get her “fixed” as soon as kittens are weaned, and they are eating cat food!! Going on 7 weeks! “

Quick Info about Momma Cat

Dear Sandra,
You are doing something really meaningful for this young momma cat, especially since she is still growing herself. It is very common for nursing queens to become quite thin because producing milk is like running a marathon every day while still trying to nourish their own bodies. Her energy and protein needs right now can be two to three times higher than normal.
The most effective and evidence-based way to help her regain her condition is to feed a high-quality kitten food, either canned, dry, or a mix of both, offered freely throughout the day. Kitten diets are more energy-dense and richer in protein and fat, which supports both milk production and her own recovery. If she prefers wet food, that can also help with hydration and is often more palatable. You can think of it as giving her “baby formula for adults”; it is concentrated nutrition designed for growth and high demand. Avoid supplements like dairy or homemade additions, since these can upset her digestion and do not provide balanced nutrition.
Since the kittens are already eating on their own, their bodies should begin to recover soon, especially once nursing decreases. Keep fresh water available at all times and monitor that she is eating well and staying bright and attentive to her kittens. If she seems weak, stops eating, or continues to lose weight, it would be best to have her evaluated by a veterinarian to rule out any underlying concerns. You are on the right track, and once she is spayed, her body will have a much easier time maintaining a healthy weight.
Kind regards,
– Dr. Paola
