Cat Illnesses

Cat illnesses are often hard to diagnose just by looking at the cat.

Cats don’t often show their pain so you may be unaware your cat is in distress. Often when the cat shows symptoms, it is already quite ill.

In nature, showing symptoms of an illness is a sign of weakness and a call to potential predators. Thus animals go the great lengths to appear healthy. As the cat is still very near its wild ancestry, this hiding of symptoms makes sense.

When the cat shows symptoms, these may be a sign of several illnesses. It can be very hard to determine which illness the cat may have.

If you suspect your cat has an illness, but you are not sure of it (like when there is occasional vomiting or sneezing), write down any symptoms you have noticed– and contact your vet sooner rather than later. Some conditions require immediate veterinary care (like when the cat is unable to pee) because they are life threatening.

If you have been wise in advance, you already have a pet insurance but even if you don’t, do not let your feline friend suffer for it. And do not try to make a diagnosis yourself - only a qualified veterinarian can do that.

Also do not try to medicate your cat with human medicines. They can be downright deadly to a cat (for example Aspirin). Also if you have old cat medications still in your cabinet, do not use them. Always, always consult a vet first.

To avoid common infectious cat illnesses, have your cat vaccinated. When you get your kitten in the first place, ask your vet which shots it needs and when.

When you took your cat as your family member, you committed yourself to its wellbeing. And if you deal with any cat illnesses as soon as possible, there is a great likelihood your cat will make a speedy recovery. Should the situation be otherwise, you can make sure your beloved pet does not suffer unnecessarily.

Some chronic diseases can be treated with constant medication (like diabetes). Some of course can’t, and then you need to be prepared to do the ultimate act of friendship and let the vet put your cat humanely asleep… (I know this is a difficult issue, but I have been there for several cats when their time came, and they all slipped away so peacefully and quietly I can assure you it causes the cat no pain or fear).

Here I shall list the most common illnesses on cats with a brief description of the symptoms, so it is easier for you to eye the list through and see which articles you would like to read. And do bear in mind I am neither a veterinarian nor expert in cat illnesses – there are general articles about these illnesses. So always consult your vet when your cat shows any symptoms of a possible illness.

Leena's Books


This book travels with the King Tut - Treasures of the Golden Pharaoh exhibition on his world tour of ten cities from March 2018 onwards

Tutankhamun: In My Own Hieroglyphs tells the story, for older children, of the life and afterlife of the famous young pharaoh in his own words. Tutankhamun tells us about the trouble he got into as a child in Akhenaten's palace in the new city of Akhetaten, and how he became a boy pharaoh. As we learn, his life changed a lot when he died as a teenager, and long years of boredom started in his tomb with only his pet monkey Fingers and his treasure for company. He did meet some of the Egyptian gods, of course, and had fun scaring off tomb robbers, but it was mostly rather dull. Then one day, some new and strange people, including a Mr. Howard Carter, arrived and began to take all the treasures out of his royal tomb. Fortunately, through the eyes of his beautiful golden mask, Tutankhamun, could have fun again traveling around the world

On my other website he continues his stories about life in ancient Egypt.

Another hilarious adventure for children with Mr Mummific, the mummy with attitude. He now tells the story of his mishaps, misunderstandings and misadventures as he leaves his tomb through the False Door to embark on the complicated and dangerous journey to the Afterlife aboard the magnificent Ship of Millions.
