Did your veterinarian recommend a therapeutic diet for your feline friend? PetSmart has exactly what you need to help support your pet. Your cat’s nutritional needs are as unique as they are. That’s why your vet may recommend a special diet that is tailored to support your kitty’s health requirements, such as: ;
Kidney Support
Urinary Health
Allergies
Digestive Care
Gastrointestinal Health
Weight Management
And More
Because these special diets are intended only for pets with specific health conditions, your vet must authorize the food before you purchase it. Visit your vet to learn more about switching your cat to a therapeutic diet and how to make the change. Always follow your veterinarian's advice when transitioning your cat to a new food plan. If you have any questions or concerns during the transition, consult your vet.
After talking with your vet and getting their authorization for a specific therapeutic diet, you can find everything your cat needs at PetSmart. PetSmart carries a wide variety of vet-authorized diets in different flavors, sizes, and both wet and dry formulas, so you’re sure to find the one your vet recommends and your kitty loves. And, with PetSmart’s convenient store locations, easy online ordering, and Autoship options, getting your kitty the vet-authorized food they need when they need it is simple.
While you’re getting your cat their vet-authorized food, why not also pick up some treats and catnip? Looking for something different than a vet-authorized diet? We carry all sorts of cat food options including dry foodfood toppersfrozen foodwet food, and more. PetSmart carries everything you need to care for your feline friend.
