Worms and internal parasites may be out of sight but are not out of mind. Pet parents that have sought the advice of a veterinarian might be on the search for cat dewormers and internal parasite care for their cats. You can find what you are looking for at The Pharmacy at PetSmart
PetSmart customers can place prescription orders through The Pharmacy website, as long as they are active prescriptions that have been prescribed by a vet in the last 12 months.
Prescriptions from a licensed veterinarian are required to purchase cat dewormer medication from The Pharmacy at PetSmart. Need to find a vet? We have you covered.
Looking for something other than dewormer and parasite medication?
Need other cat care essentials? PetSmart carries cat foodcat treats, and more that support special nutritional needs. We also sell cat toyscat towers, and cat beds to keep your feline friend happy.
