Clindamycin is given orally. If using a tablet or pill form, you must make sure your pet swallows some water after taking the medication, or the medication may cause damage to the esophagus. Do not use milk. Cats should have at least a teaspoon of water. Try offering your cat water flavored with tuna water or other liquid your cat likes. Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian. Use all of the medication prescribed, even if your pet appears well. If the entire course of treatment is not given, the infection may recur or worsen.
