Vaccinations cannot be 100% guaranteed, however if used in conjunction with proper nutrition and acceptable sanitary conditions, is is your pet's best defence against disease. Prevention through vaccination is also cost effective, as treatments for the above diseases can be drawn-out and costly, both in terms of money and distress. The immunity that a kitten has lasts longer than that of puppies, therefore they only need two vaccinations as kittens - at 10 weeks and 14 weeks. Thereafter, an annual booster vaccination is needed to protect against mainly flu-like viruses and rabies. Vaccinating your kitten can ensure a long and healthy life.
