There are plenty of vaccines available for your cat to protect him or her against a variety of conditions. However, your feline's lifestyle may make some vaccines unnecessary. And although vaccines are proven to be effective and safe in most cases, over-vaccinating your pet can have negative effects. Moreover, only certain vaccines are necessary for all purring pals.

1. Panleukopenia 

Panleukopenia, also known as feline distemper, is a disease cats get from a parvovirus. Young cats, ones between the ages of three to five months, are most likely to get feline distemper; however, any cat can get it if he or she comes into contact with the virus. The virus fights and destroys white blood cells, which are the ones responsible for fighting against infections. Once a cat contracts panoleukopenia, his or her immune system will weaken, making him or her more likely to contract another infection. Sometimes, cats exhibit no symptoms and die suddenly from it, while others may become hydrated, lethargic and lose their appetites. A fever, diarrhea and vomiting are possible as well. 

2. Feline Herpes Virus Type I

Rhinotracheitis, more commonly referred to as the feline herpes virus type I, comes from the cat getting in contact with the herpes type I virus. This particular virus can cause upper respiratory disease cats. It's possible for the cat to develop conjunctivitis, an inflammation of the area surrounding the eye. Any cat can contract the virus, but younger ones experience worse symptoms. Typical symptoms include conjunctivitis, sneezing, excessive blinking, discharge from the eyes and nasal congestion. Your pet may have become lethargic or have a fever as a result of the virus. Anorexia, enlarged lymph nodes or a poor appetite are possible as well. 

3. Feline Calici Virus

The feline calici virus (FCV) causes upper respiratory infections as well as oral infections. With over 40 types of FCV, a broad range of symptoms could develop, but the most common ones are as follows: sneezing, nasal congestion, discharge from the eyes, a runny nose, conjunctivitis, hypersalivation, fever, lethargy, enlarged lymph nodes, squinting and anorexia. Ulcers in the mouth or nose or on the lips may arise.

4. Rabies

Animals who are bitten by another animal with rabies can contract this virus. This inflammatory condition infects the gray matter in the brain. In addition, it affects the central nervous system. After your pet contracts the disease, it replicas quickly in cells throughout the muscles and in the nerve fibers. Although it can take up to a month for a pet to exhibit symptoms, your pet will get very sick soon after and may even die. Behavior changes like aggression may occur. You might notice weakness or a loss of coordination that soon is followed by paralysis. If not treated soon, the prognosis isn't positive. 

Vaccines that are unneeded or are given too close together are unsafe for your cat. You need to discuss with your veterinarian your pet's lifestyle, so he or she can determine which vaccines are absolutely needed.
