Product information

There are many reasons a cat may not be eating, including pain, stress, age, illness, and more. Inadequate caloric intake causes weight loss which can lead to malnutrition, weakening the immune system, and compromising overall health. This is why it’s essential, and at times even critical to quickly provide your cat with calories to prevent further weight loss and promote weight gain. Ready Cal Food Topper is a one-of-a-kind supplement developed to quickly provide calories and nutritional support when a cat is losing weight.

  • Why is Chicken fat the #1 ingredient? Because it smells great, and tastes even better! Enticing your cat to eat to quickly boost calories 
  • A highly palatable, easy to use powder formula! Sprinkle on top of food, or mix with warm water to create a delicious gravy (like the kind Grandma makes!)
  • Contains 9 vitamins and 6 minerals to aid in restoring overall health
  • Stimulates appetite and boosts energy
  • Made with a savory rotisserie chicken flavor that cats love
  • Vet formulated and manufactured in Vermont, free of artificial flavors and dyes.
