My sons cat is nursing 6 six week old kittens. The cat got out of the house 2 weeks ago for about 16 hours. I think the cat may be pregnant again so my son wants to get her spayed so we do not get another litter of kittens. Will it hurt the kittens to be weaned so soon? I was going to let the kittens nurse 8 weeks before finding homes for them but I do not want another litter of kittens so soon and I am not sure the mother cat is pregnant. Also, I do not think it is good for a cat to have 2 litters so close together. Any advise would be great.
