When should I get my kitten immunised?

Question

8 to 10 weeks, right?

But I read somewhere that he should be 900g in weight, and my eight-week old is only 700g.

Is he underweight? Should I wait another week or two to have him vaccinated?

Answer 1

Vaccinations for this disease at 6 weeks, 9 weeks, and 12 weeks should be administered to kittens.  

Answer 2

Their first vaccines are usually at about six weeks old.

Answer 3

No get him vaccinated now.

Answer 4

NO, do it now. Best to save your cat's life and everyone else's.
