Two mother cats - Normal?

They're fine. Many mothers will nurse and care for babies that aren't their own. They just accept it and move on. Consider yourself lucky! As long as the kittens are growing properly and seem healthy and happy....nothing to worry about. Make sure to find good homes for them and if these were unwanted....have the mommies spayed to prevent growth of the unwanted pet population! Good luck with the kitties!

This is perfectly normal. If resources (food) are plentiful enough, domestic cats will form social groups similar to prides of lions. That means female cats will band together to raise their litters in cooperation with each other - they will nurse all the kittens, and bathe them all, and take turns watching them. If a tom cat thinks the kittens are his offspring, he may play with them and help look after them some as well. But as there may be more than one tom in the area, and it is hard to know which one is daddy, it is best to keep the toms away from the kittens. Because a tom that does not think the kittens are his, may try to kill them so that the mothers will go back into heat, so he can mate with them.

completely normal. Cats in the wild often help each other nurse their kittens, siblings or not. I have had several bonded pairs of female cats give birth around the same time and that is what happened.

I won't say call a vet, but I will recommend you get them to a vet once the kittens are weaned to ensure you don't end up with any more, there are thousands of cats being put to sleep every day because there aren't enough homes. Please stop adding to the problem

Barn cats will often raise their kittens together, and if a mother cat is killed the other cats will take on her kittens. They say that the same behavior is observed in prides of lions. So there's not a problem at all!

However, I agree that you should call a vet to set up a time to spay your cats post-weaning. Keep in mind that when you find homes for your 8 kittens, 8 other kittens or cats in a shelter will not find homes.

If the moms are happy and the kittens are happy then leave them be. Nothing abnormal about it. Of course once the kittens are weaned you will need to get both cats spayed immediately but you knew that right?

This is normal. We had a cat on the farm that would go around and gather all of the kittens into one nest. If one of the mothers tried to move hers out, the older female would bring them back.

This behavior is perfectly normal. As long as the kittens are well fed, they'll be fine.

If you haven't already, please consider spaying your cats once the kittens are weaned. This will contribute greatly to their long-term health and will help to prevent the current overpopulation crisis from growing.

leave well enough alone. each momma cat has accepted the others as her own- it is perfectly ok. if you have abandoned kittens you always try to find a surrogate mom. your kittens have two mommas that can split the tasks of feeding and cleaning.

Sounds normal. I wouldn't try to stop or interfere unless one of the kittens isn't gaining as much weight as it should be. Then you may need to supplement feeding.

Last spring I had two mother cats who gave birth within days of each other and they did the same thing.....it's like this sisterhood because they rarely let each other's side.
