They are staying the cats are all playing together. We now have Linxy, Oliver, Sassy, Jasper, and Ossa. We have to put the kittens in a crate to feed them as the others will eat all the kitten food and leave the adult food. There was very little hissing when they came home so they were out and interacting with the others just hours after we brought them home. Sassy is getting along with them too. I know she will be going into hiding again in 2 weeks when we start redoing the kitchen. To much noise for her. I expect all of the cats to be hiding for part of the remodling work.
They will be closed in a bedroom while we are working for their safty and ours. We are gutting the kitchen and redoing it.
