Frequently Asked Questions (FAQs)

1. What is the best wet food for overweight cats?

That's why we recommend Smalls Cat Food as the overall best cat food for overweight cats. It's high in protein, low in carbohydrates, moisture-rich, satisfying, and doesn't have too much fat or plant matter, both of which can contribute to weight gain in adult cats.

2. What is highly digestible low fat food for cats?

Look for labels that contain chicken, lamb, rabbit, pig's heart, pig's liver, etc., at the top of the ingredients list instead of meat meal or by-products. Studies have shown that muscle meats and organs are highly digestible forms of protein for cats.

3. Is grain free better for overweight cats?

Grain-free foods are carbohydrate free – FALSE Some of these carbohydrates can lead to gastrointestinal upset. Also when the carbohydrate contents are lower, the fat and calorie amounts are higher and this can lead to overweight cats if not fed properly.
