Is this normal for a cat?

I've seen a barn cat nursing kittens bigger than she was. She had her new babies mingled in among the "teen agers".

Most mother cats will not allow them to nurse at this age, but some do. When you see the kittens going toward the mother cat, take them away from her and hold the mom. Give the kittens something to play with to divert their attention. They are using the nursing for comfort but this is not healthy for mother cat.

Take her to the vet and have her spayed. When she returns keep her in another room to heal. The kittens then may be broken of the habit.

they need to take her away from the babies. we had a cat that didithat 2, and the kitten were depleating her of what she need big time. we finally had to seperate them so she could gain back some weight. kittens should wean between 5-8 weeks. after that there is NO reason for them to still be nursing. they can actually make the mother sick.

She'll nurse them as long as she wants really (well, at least until she her body stops making milk). She sounds like a very "motherly" cat. I've seen this in my cats in the past. Stray cats and wild cats stop nursing earlier than this, but then are usually already pregnant again as well.

Yes it is ,At times in the wild,The male eats his own to force his female to go back into heat.Now its been that kids in school are still nursing. With there moms at a age of 6yrs+.

no but my cats did that too u have to take they away from the mother when they do that
