Not every mom is a good mom. In fact, most have no idea what to do when they give birth let alone take care of them.
They are still too young to be weaned so you have to take over. Here in TDKland, we recommend Goats’ milk for kittens. Cats are lactose intolerant and can’t digest cows milk. Goats’ milk is full of nutrients, probiotics and gentler on their tummies. This can also regulate their poop. If you are using the Goats’ milk concentrate, mix it with pedialyte. Pedialyte gives an extra the extra boost. Keep in mind if they seem lethargic put a dab of Karo syrup or honey in their mouth. Sometimes this is all they need to give them the added energy boost to get them eating. A smidgen of mineral oil in their formula can usually help them poop. Here are some links with good information on caring for your wee kits.
Start with Goats’ milk for a couple of days and then make them a gruel. Mix wet cat food with the Goats’ milk and put it in the bottle. Cut the opening big enough so the gruel will flow. Keep them on the gruel for another 2 weeks but wean them off the bottle. By week 8, they should eat wet food from a dish.
I hope this helps.
