Vaccinations can improve the speed and effectiveness of a cat's immune response to a respective disease or infection by stimulating it through exposure to an organism before the cat meets it for real. With proper care, attention and vaccination education on your behalf, your pet will provide you with a lifetime of joy and pleasure. This will keep your cat disease and infection free. Your vet may also recommend an additional booster vaccination at 15-16 weeks of age. These injections are usually given in the loose skin at the scruff of the cat's neck.
Some cats develop a small lump at the injection site several weeks following the injection.
This lump is a reaction to the carrier agent solution in the vaccines. Normally the lump will subside within a few weeks and should only raise concern if it lasts considerably longer than this. Let your vet know if the lump seems to bother your cat or does not seem to go away several weeks after it appeared. Always contact your vet if your cat displays any other adverse reactions to the vaccinations it has been given. Your vet or a veterinary nurse should give you a special record card containing details of any vaccinations that have been administered to your cat.
