I am currently fostering a mom and her 5 babies. The babies are 5 weeks old. Someone from my rescue begged me to take a 6 week old kitten who is alone. They thought socialization with a mom and her siblings would be important for her growing up well socialized. I put them together. (I hate putting an unknown kitten with my healthy 5- but my rescue manager gave me know choice!) The kittens are fine with the new addition. However, Mom is not at all happy. For the last 2 hours she has been hissing, growling, even going after the kitten a few times. Poor girl is terrified! I know this is not the ideal way to introduce new kitties to each other, but in this situation, is their an optimal way in including her in the family? Will mom adjust? Will the kitten be safe when I am not in the bathroom to watch mom? Help!
