Human Medication Dosage For Use In Cats


Some human medicines are also effective for cats, however the dosages are usually lower due mostly to the smaller size of the animal. Note that these medications are not FDA approved for use in dogs or cats and should only be used under the guidance of your veterinarian. Call your vet to find exact dosage requirements for your pet and ensure the safety of administration.
