Common cat illnesses

Protect your cat with MORE TH>N Pet Insurance in partnership with RSPCA

Cats of all ages can suffer from a range of medical problems and illnesses. Could you afford the costs of veterinary care if your cat suffered from any of these conditions?

Ongoing and unexpected veterinary treatments for your cat can quickly add up and become a financial burden. Cats are at risk from a range of ailments which may require expensive veterinary attention, and due to their independent nature, cats are at risk from road traffic accidents.

That's why MORE TH>N cat insurance policies offer a choice of cover to suit your needs and budget. Cat insurance can provide coverage for accidents, illnesses, surgeries, hospitalisation and much more. MORE TH>N have a choice of Premier, Classic, Basic and Accident Only Cover - compare our pet insurance policies.

Please note that Accident Only cover only covers illnesses as a result of an accident or injury that occurs within 12 months from the date of first treatment of the accident. For each policy sold, MORE TH>N will donate £20 to the RSPCA for the care of unwanted and neglected animals in England and Wales. For each Accident Only policy sold, £10 will be donated to our work*.

Common illnesses experienced by cats


We often see claims for older cats with hyperthyroidism. This is where the thyroid gland produces too much thyroid hormone. Cats may lose weight, eat and drink more, suffer diarrhea, skin conditions and nervousness and anxiety. Treatment consists of lifetime medication or surgery to remove the glands. Newer techniques use radioactive iodine to deplete the malfunctioning thyroid gland, leaving the normal gland to provide the necessary hormones.

Urinary issues

Cats are prone to certain bladder/urinary issues. They commonly suffer a type of cystitis, which is often bought about by stress. This can lead to inflammation, pain urinating, and male cats can even suffer a life threatening blockage. Treatment can range from specific foods and tablets right up to complex surgery.


We see lots of claims for cats with fractures. Their roaming lifestyle and penchant for climbing and jumping increase the risk of a fracture. Similarly they are more likely to be hit by a car than a dog, as dogs are usually on leads, whereas cats make their own way across roads. Fractures can be very expensive to repair, depending on how serious they are.


As all animals age, they are prone to arthritis. This is when the smooth surfaces of the joints become worn, and they may also become roughened and inflamed. Cats can be prone to this if they have spent a lifetime jumping and climbing. They may also be more prone to it following injuries such as falls or car accidents. The result is painful joints which may swell up, lameness (limping) and general soreness and reluctance to move. Long term medication or even surgery may be needed.


Ear infections are common in cats. There are a number of parasites and infectious agents that can cause ear infections - the most common sign of which is scratching. Cats may also shake their heads excessively, or paw at their ears. Treatment is usually with medicated drops, but sometimes tablets may become necessary.

Risk of accidents and straying

There are further risks to cats apart from illnesses - cats can be prone to accidents either in traffic or resulting from falls. Cats are also prone to straying.
