Here is something that might surprise you: Cat diseases can kill. Feline leukemia, feline distemper, rabies, feline immunodeficiency virus (FIV), upper respiratory infections, urinary tract infections and more are serious cat issues. Left untreated, any one can quickly claim your cat's life.
A cat has just one life, not nine, and it is up to you to protect it. Fortunately, protection is easier than it's ever been before. In fact, many of the cat diseases mentioned above can be avoided completely. All you have to do is make sure your cat is vaccinated according to the schedule recommended by your vet.
Contrary to what you might think, vaccinating a cat is not cruel and unusual punishment. The most it will suffer is temporary discomfort. And you would have to agree; that is an acceptable trade-off for a lifetime of prevention.
Keeping your cat indoors is another easy way to protect your cat. Many potentially fatal cat diseases are passed on to healthy cats via bites or contact with an infected cat feces or urine. Some viruses also infect inanimate objects. Keeping your cat indoors reduces your cat's risk of exposure.
No matter how well-developed, natural cat hunting instincts offer little protection against these highly contagious and deadly cat diseases. Even if you have an indoor cat, you have to vaccinate. That is because indoor cats occasionally escape, can be exposed during trips to the vet, and can come into contact with infected toys, food bowls, or brushes.
If your cat is not acting like its normal self, take it to the vet right away. Don't wait it out. Something as seemingly harmless as vomiting can be a sign of something far more serious. The vet spent years learning how to administer proper cat care - You did not. Do not take the risk.
