I have two adult cats - Princess and Thumbelina. Thumbelina has nursed on Princess even before she ever had a litter. Princess began to lactate as a result. In any event, Princess became pregnant and gave birth to a single kitten around 4 weeks ago. At first she was an attentive mother, but now that her kitten is up and running around a bit she no longer nurses her kitten, but continues to nurse Thumbelina. She doesn't reject her kitten outright, but typically won't lay down within Olivia's (the kitten's) reach. For a few days there, Olivia cried a lot and lost a lot of weight as she was a bit late in starting solid foods, but thankfully she is now eating some gruel. The adult cats's behavior disturbs me, though. Has anyone else seen this?
