The Question
“Hello Dr. Paola,
Why does my cat Curly act as though he hasn’t eaten in months right after he’s been fed? He’s a healthy weight, no health problems, just dire starvation vibes the moment his bowl is empty.” – Sean
Quick Info about Curly

Hi Sean,
When a healthy-weight cat like Curly acts ravenous right after eating, it’s often a blend of natural instincts, diet composition, and sometimes even early signs of a medical condition. Cats are obligate carnivores, meaning their bodies are biologically adapted to thrive on high-protein, low-carbohydrate diets. Many commercial kibbles, however, are high in carbohydrates to maintain shelf stability and shape. While these diets meet minimum nutritional requirements, they may not fully satisfy a cat’s biological hunger cues. Curly might feel full in terms of volume, but not necessarily satiated the way a protein-rich meal would leave him. This disconnect can result in persistent food-seeking behaviors, even right after eating.
It’s also worth considering that while Curly seems healthy now, certain medical conditions can cause an increased appetite. One of the most common conditions in middle-aged to older cats is hyperthyroidism. This condition speeds up metabolism, making cats act extremely hungry while often maintaining or even losing weight. Diabetes mellitus and certain gastrointestinal disorders can also cause polyphagia, or increased food intake. If Curly’s behavior is new or intensifying, a checkup with bloodwork is the safest way to rule out any underlying issues.
Otherwise, if he’s stable and you’re simply looking to adjust his routine, consider a consultation with PangoVet to assess whether his diet and feeding practices are meeting his needs. We can help you determine if a more satiating food option or a slight change in his feeding routine might help ease those post-meal “starvation vibes.”
Wishing Curly good health,
Sincerely,
Dr. Paola
