My 11 month old twin kittens are both pregnant, 3-4 weeks apart. Will this cause problems for either cat?
When your cat that is due first has her kittens you will need to separate them as the cat that is still pregnant will try to let the kittens suckle off her which will contract her womb and she will go into premature labour. One both litters are born you should be able to move them closer together. It they are really close they might help each other out.
