Vomiting, feline lower urinary tract disease, fleas, tapeworm, diarrhea and eye conditions are among the more common cat illnesses, according to WebMD. Symptoms vary widely but are usually discernible by observing the cat's behavior.
Vomiting is one of the most common illnesses in cats, often simply the result of hairballs. The symptoms are obvious and include heaving and drooling. Urinary tract diseases require immediate veterinary attention. Symptoms are straining or crying while urinating, bloody urine, urinating outside of the litter box, lack of appetite, and vomiting. Fleas are also very common and, fortunately, easily treatable, notes WebMD. Symptoms are scratching and licking, flea dirt on fur, irritated skin and hair loss.
Tapeworms live inside the small intestine and present with less noticeable symptoms such as vomiting and weight loss. The best evidence of tapeworms is small white flecks, like grains of rice, in feces. Diarrhea causes loose, liquid stools. There are many possible causes, and dehydration is always a concern with diarrhea. Cat eye problems include glaucoma, cataracts, conjunctivitis and inflammation, explains WebMD. Watery eyes and tear-stained fur are common symptoms, as are cloudiness of the eyes, redness, mucus, squinting and a visible third eyelid. Wiping away mucus with a moist cloth or cotton ball provides temporary relief, but veterinary attention is essential.
