Okay so I have a chi that is about 3 days away from her due date and is already producing milk. The neighbors have a pitbull which had a young kitten in its mouth yesterday. I thought it was dead at first but despite the fact that it was being caried around like a chew toy, it was okay. I took it in and gave it a bath and warmed it up. It appears to be 4-5 weeks of age. I searched for a mother or other kittens but I haven't been successful in figuring out just where this little gal came from. The weird thing is that my chi has taken to mothering it. I separated them because I don't know if this is healthy for either animal. I have been feeding the little kitten soft kitten food. So my question is will it be okay for my dog to continue mothering the kitten or should I keep them separate since newborns are on the way?
