Please consider getting your cat fixed asap so no more kittens are brought into the world...and it is a good idea to call around and find a vet that will fix each kitten and give all the vaccinations at a discount, usually can be done at about 10 weeks, 2lb....and then when you find homes for them...no one has to worry about pregnancies... you can charge the new parents what it cost you and this too helps to ensure a good home for the baby....
