If you have a sick cat, the worst thing you could do to her is neglect the disease and let her suffer, thinking that all that will go away. Untreated cat hyperthyroidism can be more dangerous that you realize, and if your cat is sick and has other health issues, her life will be joyless. It would only last a couple of years more. Only you know how important your cat is for you and that you don't want to lose a precious friend like that, do your best to make her feel better.
1. Kidney Problems
There is nothing new on the fact that when neglecting one part of your cat's body leads to other problems. When cat hyperthyroidism is left untreated, nothing can turn out right, and the kidneys are the first in line which may be affected. There are two major situations to consider. First, the preexisting renal failure that can even influence the treatment, and the second situation where the renal failure is developed after the treatment.
2. Heart Disease
The first symptoms your cat has are actually connected to a heart condition, such as high blood pressure, breathing problems, higher heart rate and many others. That's why it is recommended to find out about your cat's hyperthyroidism as soon as possible and find a proper treatment if you want to prevent some more serious problems.
3. Fatal result
This disease is mostly a problem of older cats, so for untreated cat hyperthyroidism, fatal result is inevitable. With this condition, your cat will not be able to live many years and her quality of life will be very poor, like a torture. Simply put, it is unacceptable to let your best friend live like that, especially when there is a way to help her.
Having a pet requires taking care of him all the time, not just when he is healthy. There will be some hard time as well, but nothing can justify the fact you leave cat hyperthyroidism left untreated because of lack of money or time. Many people seem to have cats for the wrong reasons, and they don't show any appreciation for love they have received throughout years. It is very simple, if you can't take care of your pet or you believe that feeding is all you have to do in the future, don't own a pet at all.
