Ive been small scale breeding rats for my collection. Tonight one of my breeder females who recently had her 2nd litter seemed very lackluster in her mothering, i observed her over some time. I noticed she has given up on anything that resembles a nest, and has neglected a few babies during nursing. I scratched her back and she kind of "woke up" to check me out and she has lost all control of her head, she has a hard time walking and just generally functioning when in motion. Can anybody identify what the issue is and what i should do about it. Any info would be great. I can euthanize her but then what do i do with the pinks? Im at a loss ive never experienced this before. Thanks in advance for any information
