Stray cats carry different diseases and some of them may be fatal. If you have cats as a pet you may want to shield them from any of the estimated 70 million stray cats who may carry some kind of disease. However, even if you protect your furry feline from outsiders, it can still contract diseases and other health problems. Below are the five most common feline health problems. Urinary Tract Infection When bacteria reach the bladder through the urethra, urinary tract infection or UTI often occurs. In cats, this condition is specifically called the FLUTD or feline lower urinary tract disease. This is characterized by difficulty in urinating, blood in the urine, fever, and fatigue. It is common in both male and female cats, especially those who are overweight. Vomiting If you have cats as a pet, you’ve probably seen your pet vomit. This is a common problem with our feline friends and the reasons are aplenty. An upset stomach may be caused by gastritis or the inflammation of the stomach. Sometimes, cats cannot digest certain foods. When the digestive system fails to break down what have been consumed, then the food may be vomited. Other minor causes include eating inedible things and eating poisonous items. Vomiting may also indicate a more serious condition. You may want to visit the vet to see if your pet is suffering from liver and kidney problems or if it has intestinal parasites or even worse, cancer. Kidney Problems As mentioned, vomiting may be a symptom of kidney disease. Other symptoms are pain during urinating, blood in the urine, excessive urination, vomiting, loss of appetite and thirstiness. Other noticeable symptoms are foul breath, weight loss and a dry coat. Kidney diseases in cats are often caused by an infection or a virus. Old age and genetics also play a part in the development of kidney problems. In some cases, cysts and tumors result to kidney diseases. If the kidney disease is left untreated and the kidney function deteriorates, this may lead to renal failure which is one of the main causes of feline mortality. Mouth Problems If you smell something bad when you’re near your pet’s mouth, it may not just be a case of halitosis. This may signify gum disease. Also, if your pet is noticeably having difficulty eating particularly when using one side of its mouth, chances are it has gum disease. Other tell-tale signs are bleeding gums and loss of energy. Ask your vet how to remedy gum disease before it leads to tooth loss. Hyperthyroidism An overactive thyroid does not bode well for our feline companion. Hyperthyroidism, according to veterinarians, is a common glandular problem that happens in cats. It is often the result of tumors on the thyroid which leads to the production of too much hormones. You’ll get a hint that your pet is suffering from an overactive thyroid if you notice a sudden drop in weight, change in appetite, vomiting, diarrhea, thirstiness and increased urination. One way to treat this disease is through radioactive iodine therapy. Having cats as a pet takes more than just feeding them and giving them a box to crawl in. It is also not just about giving in to their whim every time they do their begging-eye trick. You also need to look after their health. Take your pet to the vet regularly to avoid these common health problems.
