  • Certain medical conditions require drugs that are available only in an injectable format. In many cases, cat owners can administer these medications at home. Most cats do not mind routine injections that are given in the subcutaneous tissue. This handout provides step-by-step instructions for giving an injection. Dispose of used needles and syringes properly.

  • The easiest way to give your cat liquid medication is to mix it in with some canned food. In some cases, this is not possible, and you will have to administer the medication directly into the cat's mouth using a syringe. Before starting, make sure you prepare the syringe with the correct amount of medication. If the medication was refrigerated, you may want to warm it up by holding the syringe tightly in your hand for a minute or two. It may be helpful to have someone assist you the first few times you administer the medication. Try wrapping your cat in a blanket or towel with only its head exposed. Detailed directions for administering the medication are provided in this handout. Make sure you give your cat plenty of praise throughout the procedure and offer a special treat after giving the medication.

  • Giving pills to cats can be a challenge, even for the most experienced veterinarian! The easiest way to give your cat a pill is to hide the pill in food. Some cats will always find the pill and spit it out, so you may need to administer it directly into your cat's mouth. This handout provides a step-by-step guide to do this, along with some other options if it is still too difficult.

  • Glaucoma is a disease of the eye in which the pressure within the eye, called intraocular pressure (IOP), is increased. Glaucoma is caused by inadequate drainage of aqueous fluid. Glaucoma is classified as primary or secondary. High intraocular pressure causes damage to occur in the retina and the optic nerve. Blindness can occur very quickly unless the increased IOP is reduced. Analgesics to control the pain and medications that decrease fluid production and promote drainage are often prescribed to treat glaucoma. The prognosis depends to a degree upon the underlying cause of the glaucoma.
