PROMOTES HYDRATION DURING ILLNESS OR STRESS: Formulated to help combat dehydration, Forti Cal can be mixed with water to encourage fluid consumption in pets recovering from illness, experiencing heat stress, or needing additional hydration support. The liquid form makes it easy to administer, especially in emergency situations or with reluctant drinkers.
HIGH-CALORIE FORMULA TO SUPPORT WEIGHT GAIN: Doc Roy’s Forti Cal Liquid delivers a concentrated 210 calories per ounce from highly digestible fats, carbohydrates, and proteins, making it ideal for pets needing extra calories due to illness, surgery recovery, low appetite, or high activity levels. This energy-dense formula helps promote healthy weight gain in underweight or growing animals.
SUPPORTS ENERGY AND RECOVERY IN MULTIPLE SPECIES: Suitable for dogs, cats, horses, birds, and livestock, this supplement is an excellent source of energy for active, working, hunting, show, or breeding animals. It also supports animals recovering from illness, surgery, or nursing, helping them regain strength and maintain stamina.
ENHANCED WITH ESSENTIAL VITAMINS AND OMEGA FATTY ACIDS: Includes a broad spectrum of nutrients, such as B-complex vitamins (B1, B2, B3, B6, B12), Vitamins A, D3, C, and E, as well as omega 3, 6, and 9 fatty acids to promote immune function, skin and coat health, cellular energy, and overall wellness. These nutrients help your pet recover faster and stay healthier.
HELPS MASK MEDICATION TASTE FOR BETTER COMPLIANCE: Forti Cal can be mixed with oral medications to enhance palatability, making it easier to administer necessary treatments to finicky eaters or stressed pets. The appealing vanilla flavor encourages acceptance without added stress for both pet and caregiver.
DELICIOUS VANILLA FLAVOR PETS LOVE: The highly palatable vanilla flavor is well-accepted by a wide range of animals, encouraging consistent intake during times of decreased appetite. Whether fed directly, mixed with food, or administered with a syringe, Forti Cal ensures your pet gets the calories and nutrients they need.
