How to Safely Change Your Cat’s Food
Whether your cat’s favorite food has been discontinued or your veterinarian has recommended a prescription diet, changing food takes time. Following these steps will help your pet adjust to the taste and texture of the new food and avoid digestive issues.
Reasons to Change Your Cat’s Food
Changes may be needed if:
- Your Cat Has Reached a New Life Stage: Cat food is formulated to meet the dietary needs of cats at every stage of their lives. Your kitten may need to switch to adult food, or it may be time for your older cat to begin eating a senior food.
- Your Cat Doesn’t Like Its Food. A food change may be needed if your cat no longer likes the taste or texture of its food, or the food causes digestive problems.
- Your Cat Has a Health Condition. Your veterinarian may recommend a prescription food if your pet has a health condition, such as diabetes, kidney disease, urinary tract issues, obesity, food sensitivities, or food allergies. Cats with food allergies may develop itchy bumps on the skin that most often appear on the head and neck, according to the Cornell University College of Veterinary Medicine.
Why a Slow Approach Is Best
Your cat’s digestive system needs time to adjust to a new food. If you simply place a new type of food in front of your pet, your furry friend may experience gas, bloating, vomiting, or diarrhea after eating it. Texture, taste, and smell matter to cats. If the food seems very different, your cat may not be interested in trying it.
How to Introduce a New Food
Mix the new food with the old to ease the transition. For the first two days, mix 25% of the new food with 75% of the old food. On the third and fourth days, try a 50/50 mix of old and new food. Mix 75% of the new food with 25% of the old food on the fifth and sixth days. Offer only the new food on the seventh day.
This is a general schedule that may not be ideal for all cats. If your cat is a picky eater or has a sensitive stomach, you may want to introduce the new food more gradually.
Tips for Success
Your cat may be more likely to accept the new food if you follow these tips:
- Look for Similar Ingredients. If your cat likes poultry and beef flavors and hates seafood, try a new food that includes the preferred ingredients.
- Pay Attention to Texture. Your pet may be more likely to accept a new food if it has a similar texture to the current food.
- Mix Well. Your cat may avoid the new food if you put both foods side-by-side in your pet’s dish. Mixing the food thoroughly helps the flavors blend together.
- Warm It Up. If you’re introducing a new kind of wet food, warm it slightly. Warming releases tempting aromas that may make your cat more interested in the food.
- Pay Attention to Warning Signs. Your cat may vomit or have diarrhea if you introduce new food too quickly. Vomiting and diarrhea may also mean that the new food is upsetting your pet’s digestive system. If this happens, lengthen the introduction schedule and temporarily reduce the amount of the new food offered. For example, add 10% of the new food instead of 25%. If symptoms continue, let your veterinarian know.
- Don’t Let Your Cat Starve. Some cats may stop eating if they don’t like the taste or texture of a new food. Unfortunately, skipping meals increases the risk of a serious liver condition that may happen if your cat doesn’t get enough protein. PetMD recommends calling your veterinarian if your cat doesn’t eat at least three tablespoons of food every day.
