Maui is great with other cats and with humans! He is very affectionate and is a lap cat! Maui came to the shelter as a kitten because he was having urination concerns.  Maui has undergone testing and diagnostics and has been diagnosed with a rare disease called Diabetes Insipidus (DI).  DI causes increased urination, dilute urination, and increased thirst and drinking.  The brain produces a hormone called vasopressin which regulates the body's retention of water.  Maui's lack of vasopressin may be congenital.Maui receives exogenous vasopressin administration called desmopressin or DDAVP.  This comes as a nasal spray in which we have removed the liquid and placed it into a sterile vial. The liquid is diluted with 0.9% saline solution.  Using an insulin syringe, draw up 2 units and administer this under the skin or SQ.  He has tolerated this medication well.The DDAVP decreases the amount of urination and water consumption.  Without the medication he drinks about 4 cups of water and will soak 2 litter boxes with urine within a 24 hour period. Please provide him with a large water bowl and 2 litter boxes.  If he does not have access to water he can become significantly dehydrated and ill.  The DDAVP medication is not mandatory as long as he can drink as much water as he needs and urinate appropriately.  Many cats live without the medical treatment.  If this is the case, please monitor him every 12 hours and monitor his litterbox.  He should be urinating at least every 6-12 hours if not on any medications.I am great with other cats and I LOVE humans!
