You need to change your cat's food: new brand, veterinary diet, change of flavor. The problem: the cat **refuses**. Hunger strike. Dangerous. Let's see how to make the switch without trauma.

## Why the cat refuses new food

### 1. Food neophobia

All cats have **neophobia** towards new foods:
- Evolutionary trait (in nature, new foods can be toxic)
- Strict carnivores = conservative food choices

### 2. Familiar food = safety

The cat associates known food with:
- Survival
- Routine
- Emotional safety

### 3. Taste and texture

Different food = different sensation:
- Texture (pâté vs chunks)
- Flavor
- Smell

Even small differences can be off-putting.

### 4. General stress

Diet changes during stressful periods:
- Recent move
- New animal
- Home repairs

Make refusal more likely.

## The risk of "prolonged hunger"

**Never force a cat to fast** to accept new food.

### Hepatic lipidosis

Cat fasting **3-4 days** → body mobilizes fats → accumulation in the liver → **liver failure**.

Particularly dangerous in:
- Overweight cats
- Senior cats
- Sick cats

**Symptoms:** jaundice, vomiting, anorexia, lethargy.

**Treatment:** long, costly, guarded prognosis.

## The correct transition: 7 weeks

**Gradualness is key.** Never make abrupt changes.

### Week 1: introduction

**90% old food + 10% new food.**

- Mix well
- Ensure the cat eats everything
- No digestive symptoms

### Week 2: increase

**80% old + 20% new.**

### Week 3

**70% old + 30% new.**

### Week 4

**50% old + 50% new.**

### Week 5

**30% old + 70% new.**

### Week 6

**10% old + 90% new.**

### Week 7

**100% new food.**

## Strategies for "stubborn" cats

### Strategy 1: temperature

Warm the new food:
- 30 seconds in the microwave (test temperature)
- Water bath
- Warm water on top

Heat enhances aromas → increases palatability.

### Strategy 2: add "toppings"

For the first days of transition:
- Spoonful of favorite pâté
- Chicken broth (no salt, no onion)
- Natural tuna (small amount)

On top of the new food.

### Strategy 3: same brand, different flavor

Easier transition between:
- Different flavors of the same brand
- More difficult between different brands

### Strategy 4: same consistency

Easier transition between:
- Pâté → pâté
- Chunks → chunks
- More difficult between pâté → chunks

### Strategy 5: serene environment

Diet change in:
- Quiet area
- Away from other animals
- Same bowl

### Strategy 6: rituals

Maintain:
- Same meal times
- Same bowl
- Same area
- Sweet voice during

The food changes but the "ritual" remains.

### Strategy 7: patience

Some cats accept within 2-3 weeks. Others require **months**. Never force.

## The "special veterinary food"

When the vet prescribes specific food (renal, diabetic, etc.):

### Typical difficulties

- "Less palatable" flavor
- Different appearance
- Cat's reluctance

### Specific strategies

#### 1. Ultra-slow transition

8-12 weeks instead of 6-7.

#### 2. Soaking with broth

Homemade chicken broth (no salt, no onion) on top of the medical food.

#### 3. Transition wet food

Start with medical wet food, then add medical kibble.

#### 4. Heating

Always.

#### 5. Treat after the meal

Special snack to "reward."

## Signs of refusal

### Complete refusal

- Sniffs and walks away
- Doesn't touch food
- Leaves the bowl

### Partial refusal

- Eats little
- Skips entire portions
- Appears "frustrated"

### Stress from change

- Vomiting
- Diarrhea
- Lethargy
- Excessive vocalizations

→ **Slow down transition.**

## When to worry

### URGENT veterinary visit if:

- **48 hours without eating** (adult cat)
- **24 hours without eating** (kitten)
- Lethargy
- Persistent vomiting
- Weight loss > 5%

## What NOT to do

### ❌ Abrupt change

100% new food immediately = disasters:
- Total refusal likely
- Diarrhea
- Vomiting
- Stress

### ❌ Forcing with a syringe

Only in medical emergencies with veterinary instructions.

### ❌ "Starve it" to make it accept

Dangerous. Risk of lipidosis.

### ❌ Mixing food with "too obvious" tricks

Tuna or snacks that dominate the flavor - the cat learns to eat only "with tuna."

### ❌ Changing food every 2 days

Confuses the cat. Keep one brand/flavor for at least 2-3 months before evaluating others.

## Prescribed diets: management

### Renal diet (Hill's k/d, Royal Canin Renal, Specific Kidney)

For renal failure. Generally accepted flavor. Standard transition.

### Urinary diet (struvite)

For cystitis, stones. Good palatability.

### Diabetic diet (Y/D, Royal Canin Diabetic)

Low in carbohydrates. Intense flavor, generally appreciated.

### Allergy diet (hydrolyzed)

Often less tasty. Very gradual transition.

## Introduction of wet + dry

### From dry alone to mixed

Week 1: only kibble + 1 teaspoon wet mixed in
Week 2: kibble + 2 teaspoons wet
...
Week 6: 50/50

### From wet alone to mixed

Gradually replace the afternoon wet food with kibble.

## The "acceptance test"

Before purchasing large amounts:

1. Buy **small package** (50-100 g)
2. Try it as a "snack"
3. If accepted: proceed
4. If refused: change flavor/brand

Avoid throwing away 5 kg of unwanted food.

## Wet food vs dry: more difficult changes

### From wet to dry

**More difficult.** The cat prefers wet (more flavor, more water):
- Very gradual transition
- Adding water to kibble
- Heating

### From dry to wet

**Easier.** Wet is more palatable.

## Premium brands

### More palatable (generally)

- Almo Nature
- Schesir
- Carny (Animonda)
- Cosma
- Applaws

### Veterinary less palatable

- Hill's
- Royal Canin Veterinary
- Purina Veterinary

**Exception:** some cats love veterinary brands. Variable.

## The "chronically picky" cats

Some cats always refuse new foods. Strategies:

### 1. One brand for life

If you find the right one, don't change unless necessary.

### 2. Variation of flavor from the same brand

More tolerated.

### 3. Veterinary behaviorist

In severe cases.

### 4. Appetite stimulants

Mirtazapine prescribable by the vet.

## When change is mandatory

For medical reasons, even picky cats must change:

### Extreme strategies

1. **Veterinary hospitalization** for forced assistance
2. **Nasal-gastric tube** (for very sick cats)
3. **PEG tube** (feeding through the stomach)

Always under veterinary supervision.

## Real times

In studies:
- **70% of cats** accept new food in 3-4 weeks
- **20%** require 5-8 weeks
- **10%** need special strategies

## In short

Changing a cat's food is an art of patience. Transition of **6-8 weeks** (longer if necessary) with increasing percentages, heating, a serene environment, no forcing. **Never starve** the cat: risk of hepatic lipidosis. If it absolutely refuses everything, consult the vet. The right food is important: insist wisely, never violently. The cat adapts — just wait.
