i have a huge female rat shes about 8 months old and had her second litter. the first litter she starved her pups to death than ate most now shes had her second litter 12 pups and i noticed there are 8 left now? and one is looking very skinny the rest look good as long as she stops eating them? i dont know why she is doing this i feed her mazuri 6f and even give her snacks every other day. i figured i would give her a second chance but if these 8 pups left don't become her food than she will not be fed to my huge pastel. any thoughts why this could be happening?
