There has been a lot written about vaccinations and I urge you to read the most current recommendations. It is very important that kittens receive their last kitten booster at 16 weeks or older. Finishing kitten vaccination at 12 weeks will not cover them.
I am against over-vaccinating and I don't think there is any need for yearly boosters - the current recommendation is every three years after the cat has received it's first year vaccine.
Please visit The World Small Animal Veterinary Association (WSAVA) for the most current guideline:
Please do not buy kittens from me if you intend to de-claw them! There are other ways to deal with scratching cats. You can keep your cat's nails trimmed, buy them rope scratch posts and other scratching toys.
