A note before we begin.. the observations in this article are not drawn from published research or clinical trials. They reflect personal experience gathered over three years working with Raw Meow customers and their cats. Readers seeking peer reviewed evidence should look elsewhere. What follows is grounded in direct, real world observation rather than formal study.
The Pattern We've Observed
One behaviour we see consistently, and which we refer to informally as "gorging", occurs in the early stages after a cat transitions from a commercial diet to raw. Many cats appear notably hungrier during this period, requesting significantly more food than they consumed previously, sometimes asking for extra meals, sometimes finishing portions faster than usual, sometimes simply pacing and vocalising around feeding time in a way they didn't before.
This is not something we see in every cat that transitions, but it is common enough, and consistent enough across different households and different cats, that we felt it was worth addressing directly. It tends to catch new raw feeders off guard, particularly those coming from a strict portion controlled dry food routine, where an increase in demand can feel like something has gone wrong.
Why We Think This Happens
There are two explanations we consider plausible, though neither has been formally tested and we want to be upfront about that.
The first is that once a cat begins receiving the nutrients and protein levels its body actually requires, rather than the diluted or filler heavy composition of many commercial diets, it responds by consuming as much as it can while that food is available. In effect, the body behaves as though it isn't yet convinced this new, more nutritionally complete food source is going to stick around.
The second is that the cat is compensating for an existing nutritional shortfall built up over time under its previous diet. On this theory, the increased appetite is less about uncertainty and more about the body actively working to correct a deficit, taking in more than usual until that gap is closed.
We don't know which of these, if either, is the full explanation. It's entirely possible both play a role, or that the true cause is something else altogether. What we can say with more confidence, purely from repeated observation, is that the pattern itself is real and reasonably predictable.
How Long It Tends to Last
In our experience, this phase is temporary. It typically resolves within one to two months, though the exact timeframe varies from cat to cat. Some cats settle within a couple of weeks. Others, particularly older cats or those with a long history on dry food, can take closer to the two month mark before their appetite levels off.
During this window, food intake is often noticeably higher and less predictable than it will eventually become. Once the phase passes, most cats shift into a much more consistent pattern, eating a similar amount at each meal and showing far less urgency around feeding time.
Our Recommendation
Based on what we have observed across many transitions, we recommend feeding according to demand during this period rather than working to a fixed portion size. If your cat is asking for more, our advice is to give it to them.
Restricting food in an attempt to manage the behaviour appears, anecdotally, to extend the gorging phase rather than shorten it. Whether the cat is genuinely catching up on nutrition or simply adjusting to a new food source, working against that process by limiting intake doesn't seem to resolve it any faster, and in our experience often makes the demanding behaviour more persistent.
What Comes After
Once the gorging phase passes, most owners report a fairly clear shift. The cat begins to self regulate, eating a consistent amount rather than continually asking for more, and mealtimes become noticeably calmer and more predictable.
This is also, in our experience, around the time the physical changes commonly associated with raw feeding start to become visible. Coat condition is the one we hear about most often, along with general energy levels. These are observations reported to us by customers over time, not claims about guaranteed outcomes for any individual cat.
When It's Worth a Second Look
Increased appetite on its own, in the context of a recent raw transition, is not something we consider a red flag. That said, gorging as we've described it here is specifically about increased hunger and demand for food, not about other symptoms.
If what you're seeing goes beyond appetite, for example sudden weight loss, vomiting, diarrhoea, lethargy, or a refusal to eat, that combination doesn't fit the pattern we're describing and is worth raising with your vet rather than assuming it will resolve on its own.
In Short
If your cat has recently moved onto raw and seems unusually hungry, this is, in our experience, a common and self limiting phase rather than something to be concerned about. Feeding according to demand, rather than restricting intake, tends to be the more effective approach based on what we've observed across many transitions.
Most cats settle within a couple of months, and many owners find that the visible benefits of raw feeding start to show around the same time their cat's appetite finds its new normal
