Yes I have to get a couple of spray bottles for starters. I have let S Mary in the house, she is typical cat checking out the new space in only a few rooms. But with no encounters with other cats. Taking things slow seems just ok. Mommy cat I feel is good to help socialize Mary. She is a non dominate cat but very engaging with others. She was tremendous with Dexter who grew up without siblings and was very rough with her. She is sweet but smart. Been thinking who to put down with her. I have her 3 babies who she doesn't recognize. And they fear her. Mommy's 3 ...4 year old babies are all very timid. That leaves the older cats Larry, Curly, Dexter and Mommy. Thanks for your help, it is immeasurable. :-)
