I have a cat I have had for about three months now that I adopted from the Humane Society. This morning I picked her up to look out the window with her at the birds in the trees when I noticed a mama cat and her kitten running through the back yard. I went out and was not able to catch the mom but got the kitten. My husband and I guess she is about five weeks old but maybe a little younger. The mom has come back several times looking for her baby and for that I feel bad but I feel she is safer in the house with us then running the streets. One of the problems I am having is my other cat keeps trying to wrap herself around the kitten and cleans then starts biting her all over. Keeps going for the babies throat. I would be thankful for any advice. It bothers me that mama cat keeps coming back looking for her baby and I can't catch her and also my cat going for the babies throat.
