## Safe Weight Loss for Cats
### Important Warning
**NEVER crash diet a cat:**
* Rapid weight loss causes hepatic lipidosis
* Can be fatal

* 1-2% body weight per week maximum
### Step 1: Veterinary Consultation
**Essential First Step:**
* Rule out medical causes
* Establish target weight
* Create safe timeline
* Discuss appropriate diet
* Schedule monitoring visits
### Step 2: Calculate Calories
**Guidelines:**
* Vet calculates ideal caloric intake
* Typically 20-30 calories per pound of IDEAL weight
* Accounts for activity level
* Adjusts based on progress
### Step 3: Measure Food Precisely
**Best Practices:**
* Use measuring cups or scale
* Weigh food for accuracy
* Account for ALL food (treats count!)
* Divide into multiple meals
### Step 4: Choose Appropriate Food
**Options:**
* Prescription weight loss diet
* High-protein, low-carbohydrate
* Increased fiber for satiety
* Wet food (fewer calories, more volume)
**Avoid:**
* Drastically reducing current food (nutrient deficiency)
* "Light" foods without vet guidance
* Carbohydrate-heavy foods
### Step 5: Increase Activity
**Safe Exercise:**
* Short, frequent play sessions
* Interactive toys (wand toys, laser pointers)
* Food puzzles
