Senior cat health problems

Here we have discussed some of the cat health issues that are mostly seen in senior cats. Typically, due to overage and lack of immunity, some chronic diseases may happen to your cat. 

Chronic kidney disease or renal failure

Renal failure is a frequently occurred disease and may become fatal compared to other senior cat health problems. Animal kidneys work as the primary filter structure for the removal of waste materials. However, through urination, kidneys remove these waste products. But, kidney functions hamper when they get weak due to aging. The symptoms of renal failure include the urge to drinking water, frequent urination, loss of appetite, and nausea, or vomiting. 


Hyperthyroidism is also a common health problem in cats, especially older cats. However, if the production of the thyroid hormone in the thyroid gland overloads, hyperthyroidism occurs. The most common symptoms of this disease are diarrhea, drastic weight loss despite overeating, vomiting, and increased urination. 


Another common health issue in senior cats is Arthritis. Because of aging, your feline suffers from bone joint pains and weakness. However, this happens when the decay of bones increases gradually over time. If your cat has Arthritis, then that will lessen his daily activity speeds. Moreover, he will sleep most of the time and often complain about joint pains.

Heart problem

A weak heart condition in senior cats is quite normal. However, tiredness, asthma, cough, weight loss, and weakness in limbs indicate the feline heart problem. So, if you ever notice these symptoms at a time in your senior cat, consult your veterinarian. Your vet may perform an electrocardiogram or echocardiogram to confirm the heart problem.

Oral disease

From various types of oral disease, many complications may occur in aged cats. However, swollen gums, bleeding from teeth, and smelly breath are common in them. Besides, difficulty in eating, sore throat, loose teeth, etc. can happen because of aging. Nevertheless, early diagnosis can treat oral disease and infections successfully. 


Type 2 diabetes is a frequently occurred disease in senior cats. It is a condition when the animal body suffers from the incapability of applying insulin properly. However, the risk of type 2 diabetes is more in obese cats. Nonetheless, weight loss, weakness, increased urination, and dull skin is common symptoms. And, for treatment, your vet may suggest medications to control the insulin level. 


Hypertension is a serious health issue in aged cats. Besides, this disease has an association with other common cat health problems. To clarify, kidney disease, hyperthyroidism, heart disease, etc. are interconnected with hypertension. Slow or irregular heart sound and weak vision are the main signs of hypertension in cats. 

In most health problems in senior cats, your pet doctor may suggest some medications and changed diet plans. 

Kitten health problems

Cat health problems, especially kitten health issues, are not serious most of the time. However, their immune system is fragile. Therefore, you need to make some effort to solve their health issues.  

Intestinal worms’ infection

Normally, hookworms, roundworms make ways to the cat’s intestine and cause intestinal worms’ infection. Also, whipworms cause illness in kittens. Because of intestinal worms’ infection, they lose weight and suffer from severe diarrhea. Thus, it hampers their growth. From the age of eight weeks, you should consult your vet to deworm them. 


This illness is somewhat an uncommon disease. Coccidia happens if your kitten suddenly swallows poop. However, there is no vaccine for it, so be careful when your kitten has diarrhea. Moreover, dehydration and losing the interest of food are other signs of it. Veterinarians normally test the stool to check the existence of coccidia. 


Conjunctivitis is a contagious infection, which frequently occurs in kittens. It happens when the eyeball covering membrane becomes infected. Your kitten’s eyelids may be affected too. The color of your cat’s eye changes into pink. Mostly, you will see sore eyes with transparent liquid discharge. However, veterinarians suggest eye-drops for primary stage infections. For severe soreness, the doctor may prescribe antibiotics, relevant antibacterial solution, and some home remedies.

However, this disease transmits from a mother cat to their kittens. Moreover, the symptoms occur immediately after birth. Sometimes it takes around 6-8 weeks to show. The most common symptoms are severe exhaustion, muscle squeezing, dehydration, food reluctance, and difficulty in breathing.  

Feline Cerebellar Hypoplasia

Feline Cerebellar Hypoplasia is a neurological cat health problem. FCH happens right after one or two weeks of the birth of the kitten. Moreover, Feline Cerebellar Hypoplasia can occur at some stage in the conception period. This disease reduces the ability of movement typically. Besides, it affects the neurological control in kittens.

Feline Leukemia Virus 

Feline Leukemia Virus (FeLV) is tremendously transmittable. Moreover, it can spread through usual skin contacts and from mother to kitten. Generally, this disease affects the normal immune system of kittens. Consequently, it increases the possibility of death from other diseases in kittens. However, vaccination can prevent the Feline Leukemia Virus


Almost all cat breeds suffer from one or more major health problems throughout their lives. However, several health issues occur in certain breeds of cats only. Moreover, there are a few differences in the disease occurrence methodology in young and older cats. Besides these, we cannot ignore the possibility of a rare illness in cats.
